Project : SOHO - LASCO/EIT
Name : COMBINE_MVI
Purpose : Insert frames from one mvi into another to create combined movie.
Explanation : This procedure combines movies from different telescopes by inserting
frames from mvi1 inside mvi2. The cadence is determined by mvi1 (the
inner field). The nearest frame in time from mvi2 is found for each
frame of mvi1. The mvi1 frame is then CONGRID'd to the pixel size
of mvi2 (the outer field) and inserted into the mvi2 frame.
WRUNMOVIE is then called for animation.
Use : COMBINE_MVI, mvi1, mvi2, CUTOFF=cutoff, /PROMPT
Example: IDL> COMBINE_MVI, 'c2.mvi', 'c3.mvi', CUTOFF=5.5
Inputs : mvi1 : Filename of mvi file for inner field.
mvi2 : Filename of mvi file for outer field.
Outputs : None.
Keywords : /PROMPT : Set this keyword to be prompted for centers and scale factors.
Otherwise they are read from .mvi files.
CUTOFF=cutoff : Set this keyword to the boundary desired between the inner and
outer fields (Units of Rsun). Defaults are:
IF EIT is inner image : cutoff is 1.3
IF C1 is inner image : cutoff is 2.2
IF C2 is inner image : cutoff is 5.5
SPLIT_COLORS: Set this keyword to split color table in
output mvi between those in the input mvis.
INNER : Setting this keyword will CONGRID the outer field image (mvi2) to the
pixel size of the inner field image (mv1). It uses the portion of the
original image that corresponds to the new
field of view for speed.
FOV : Set this keyword to the desired size (in pixels)
of the final movie. If the final dimensions are larger than 1024^2, the program
prompts for values. (Default = size of mvi2 < 1024). FOV can either 1- or
2-element array.
HDROUT : Save the movie with outer image header values; default is to use inner image
NOLABEL: Do not add time stamp
LESS: If set, outer frame is always after inner frame; otherwise outer frame
is closest in time
MATCH: Match frames 1-to-1 to smallest array
Calls : WRUNMOVIE
Category : Image Processing/Display.
Prev. Hist. : None.
Written : Scott Paswaters, NRL, Apr 1997.
Modified : SEP 03 Apr 97 - Released.

Project : SOHO - LASCO/EIT
Name : MKMOVIE
Purpose : Load FITS files into pixmaps and call WRUNMOVIE for animation.
Explanation : This procedure sorts the images by time, reads them, and
normalizes to the exposure time of the first image.
WRUNMOVIE is called to start a widget interface for the
animation sequence. The on_off_diff keyword results in a movie
where each on line image is displayed with a nearby offband image
subtracted. Default is to rectify images by CROTA1.
Use : MKMOVIE, list, bmin, bmax, /TIMES, /DIFF, /NO_NORMAL, /NO_SORT, $
UNSHARP=unsharp, PAN=pan, COORDS=coords, BOX=box, $
/RATIO, /USE_MODEL,/FLAT_FIELD,/ON_OFF_DIFF,/MASK_OCC,/LG_MASK_OCC
/RUNNING_DIFF, /RADIAL, /DEGRID, /FIXGAPS, /LOG_SCL, /SQRT_SCL, $
FILL_COL=fill_col, SAVE=save
Example: IDL> MKMOVIE, 'list960123', -100, 100, /DIFF
Example: If you want to display BYTARR images straight from the FITS files without
any scaling use:
IDL> MKMOVIE, 'list', 0, 255, /NO_NORMAL, /NO_SORT
Inputs : list : Name of file containing names of FITS files.
Or a STRARR of the image names.
bmin, bmax : Minimum and maximum DN for BYTSCL.
Outputs : None.
Keywords : The following keywords apply to all telescopes (C1,C2,C3,EIT)
DBIAS = amount (DN) to subtract from raw image, in addition to bias
/VERBOSE : Print more info about each frame
LABELPOS : Set equal to 2-d array containing x-pos and y-pos of lower left
corner of label printed on each frame; default is [10,10] for full frame
/NORECTIFY : DO NOT Rectify images to solar north up based on roll value in
$ANCIL_DATA/attitude/roll
/KEEP : Tell wrunmovie not to erase pixmaps
/TIFF : Save movie as TIFF frames
/BAD_SKIP : Skip bad frames based on nz median
/C23 : Use occulter mask for C2
/NOCAM : Do not print detector name with time
/HIDE_PYLON: hide pylon based on pixel values
/SQUARE : Makes square 480x480 frames for video (also set /VIDEO)
/NOEXPCORR : Don't do exposure time correction, but subtract bias
/OUTER : Set along with MASK_OCC to fill in outer mask only
/STAIND : Start with this position in the input file (for output filenames)
/NX,/NY : Output size in pixels (superceded by PAN)
/VIDEO : Generate frames ready to be saved as PICT files for video
/SDIR : Directory to save video frames in
/CREM : Remove cosmic rays using REMOVE_CR (2 image) procedure;
Set CREM = 2 if you wish to define an area not to do CR removal
/LOGO ; Add LASCO logo to bottom right corner
/AUTOMAX : Compute bmin and bmax based on median
/LEE_FILT : Apply Leefilt function to filter noise.
/TIMES : Set this keyword to display date and time in images.
/DIFF : Set this keyword to make a difference movie. The
first image is subtracted from all subsequent images.
/RUNNING_DIFF : Make a difference movie, subracting the preceding image.
/NO_NORMAL : Don't normalize exposure times to that of the first image or subtract bias
/NO_SORT : Don't sort by time in header.
UNSHARP : Set this keyword to make a movie of unsharp masked images.
The value of the keyword if any is set to the size of the
unsharp mask, default=25
Example: A value of 9 would form a 9x9 unsharp mask
/RATIO : If using diff or running_diff display data as ratio of image/reference frame
/MASK_OCC : applies a sun sized circle and removes the internal part of the image
/LG_MASK_OCC:applies a sun sized circle and removes the part of the field to 1.2Rsun
for C1 (especially good for the longer 100s exposures).
For C3 the pylon is masked
/LOG_SCL : Applies ALOG10() function to image before byte scaling
/SQRT_SCL : Applies SQRT() function to image before byte scaling
/FIXGAPS : Set to 1 to fill data gaps in image with color specified by FILL_COL
Set to 2 to fill data gaps in image with values from previous image
FILL_COL : Set this keyword to the color index to use for data gaps and occ masks.
SAVE : For use in batch mode. Set this keyword to the name of the .mvi file
to save as. Routine will save movie and then exit.
PAN : Default is to resize images to pixel size of the first image. Set this
keyword to perform additional scaling. Example: set to 0.5 for 2x2 rebinning.
COORDS : Set to 4 element array of image coordinates to use relative to 1024x1024 image.
Example: COORDS=[0,1023,128,895] for C2 Equatorial Field
BOX : Set to 4 element array of image coordinates to use for box normalization
relative to (rectified) 1024x1024 image. Images are scaled relative to average counts
in box of first image. Example: BOX=[461,560,641,740]
REF_BOX : Set to avg counts specified in BOX otherwise first image is used
: The following keywords apply only to C1
/ON_OFF_DIFF: differences each on line image with an image taken at a continuum wavelength
/FLAT_FIELD : normalizes each image by a door closed image to remove the solar spectrum
/RADIAL : applies a radial filter
: The following keywords apply only to C2 and C3
USE_MODEL : If using diff or running_diff use background corona model
as base frame. USE_MODEL=1 for closest average (any_year) monthly model
USE_MODEL=2 for closest monthly model
USE_MODEL=3 for for overall yearly model
USE_MODEL= array to do subtraction or ratio with
: The following keywords apply only to EIT
/DEGRID : applies the degridding algorithm

Name : MKMOVIE0 (obsolete version of mkmovie.pro)
Purpose : Load FITS files into pixmaps and call WRUNMOVIE for animation.
Explanation : This procedure sorts the images by time, reads them, and
normalizes to the exposure time of the first image.
WRUNMOVIE is called to start a widget interface for the
animation sequence. The on_off_diff keyword results in a movie
where each on line image is displayed with a nearby offband image
subtracted.
Use : MKMOVIE, list, bmin, bmax, /TIMES, /DIFF, /NO_NORMAL, /NO_SORT, $
UNSHARP=unsharp, PAN=pan, COORDS=coords, BOX=box, $
/RATIO, /USE_MODEL,/FLAT_FIELD,/ON_OFF_DIFF,/MASK_OCC,/LG_MASK_OCC
/RUNNING_DIFF, /RADIAL, /DEGRID, /FIXGAPS, /LOG_SCL, /SQRT_SCL, $
FILL_COL=fill_col, SAVE=save
Example: IDL> MKMOVIE, 'list960123', -100, 100, /DIFF
Example: If you want to display BYTARR images straight from the FITS files without
any scaling use:
IDL> MKMOVIE, 'list', 0, 255, /NO_NORMAL, /NO_SORT
Inputs : list : Name of file containing names of FITS files.
Or a STRARR of the image names.
bmin, bmax : Minimum and maximum DN for BYTSCL.
Outputs : None.
Keywords : The following keywords apply to all telescopes (C1,C2,C3,EIT)
/BAD_SKIP : Skip bad images based on NZ median
/DBIAS : Adjust image bias by given amount
/NOEXPCORR : Don't do exposure time correction, but subtract bias
/OUTER : Set along with MASK_OCC to fill in outer mask only
/STAIND : Start with this position in the input file (for output filenames)
/NX,/NY : Output size in pixels (superceded by PAN)
/VIDEO : Generate frames ready to be saved as PICT files for video
/SDIR : Directory to save video frames in
/CREM : Remove cosmic rays using REMOVE_CR (2 image) procedure;
Set CREM = 2 if you wish to define an area not to do CR removal
/LOGO ; Add LASCO logo to bottom right corner
/AUTOMAX : Compute bmin and bmax based on median
/LEE_FILT : Apply Leefilt function to filter noise.
/TIMES : Set this keyword to display date and time in images.
/DIFF : Set this keyword to make a difference movie. The
first image is subtracted from all subsequent images.
/RUNNING_DIFF : Make a difference movie, subracting the preceding image.
/NO_NORMAL : Don't normalize exposure times to that of the first image.
/NO_SORT : Don't sort by time in header.
UNSHARP : Set this keyword to make a movie of unsharp masked images.
The value of the keyword if any is set to the size of the
unsharp mask, default=25
Example: A value of 9 would form a 9x9 unsharp mask
/RATIO : If using diff or running_diff display data as ratio of image/reference frame
/MASK_OCC : applies a sun sized circle and removes the internal part of the image
/LG_MASK_OCC:applies a sun sized circle and removes the part of the field to 1.2Rsun
for C1 (especially good for the longer 100s exposures).
For C3 the pylon is masked
/LOG_SCL : Applies ALOG10() function to image before byte scaling
/SQRT_SCL : Applies SQRT() function to image before byte scaling
/FIXGAPS : Set to 1 to fill data gaps in image with color specified by FILL_COL
Set to 2 to fill data gaps in image with values from previous image
FILL_COL : Set this keyword to the color index to use for data gaps and occ masks.
SAVE : For use in batch mode. Set this keyword to the name of the .mvi file
to save as. Routine will save movie and then exit.
PAN : Default is to resize images to pixel size of the first image. Set this
keyword to perform additional scaling. Example: set to 0.5 for 2x2 rebinning.
COORDS : Set to 4 element array of image coordinates to use relative to 1024x1024 image.
Example: COORDS=[0,1023,128,895] for C2 Equatorial Field
BOX : Set to 4 element array of image coordinates to use for box normalization
relative to 1024x1024 image. Images are scaled relative to average counts
in box of first image. Example: BOX=[461,560,641,740]
REF_BOX : Set to avg counts specified in BOX otherwise first image is used
: The following keywords apply only to C1
/ON_OFF_DIFF: differences each on line image with an image taken at a continuum wavelength
/FLAT_FIELD : normalizes each image by a door closed image to remove the solar spectrum
/RADIAL : applies a radial filter
: The following keywords apply only to C2 and C3
/USE_MODEL : If using diff or running_diff use background corona model
as base frame. USE_MODEL=1 for closest average (any_year) monthly model
USE_MODEL=2 for closest monthly model
USE_MODEL=3 for for overall yearly model
: The following keywords apply only to EIT
/DEGRID : applies the degridding algorithm
Calls : WRUNMOVIE
Side effects: Creates multiple pixmaps.

Name : MVIPLAY
Purpose : Widget tool to display animation sequence.
Explanation : This tool allows the user to view a series of images as
an animation sequence. The user can control the direction,
speed, and number of frames with widget controls.
Click any mouse button inside draw window to bring forward/hide
control widget.
Use : IDL> MVIPLAY [, mvifile, /DISK, /FITSCREEN, START=start, SKIP=skip, LENGTH=length]
Without any inputs, program will prompt user to select an existing .mvi file.
Example : IDL> MVIPLAY
Or you could have one argument, the .mvi file you want to load.
Example : IDL> MVIPLAY, 'mymovie.mvi'
Use keyword /DISK to play movie from disk instead of loading into RAM.
This option is useful for viewing large movies on systems with a limited
amount of RAM. The maximum speed of the movie will depend on the transfer
speed of the hard drive or CD-ROM and will be slower than loading into RAM.
Example : IDL> MVIPLAY, 'mymovie.mvi', /DISK
Use keyword /FITSCREEN to redimension image to 640x480 (does not work with /DISK)
Example : IDL> MVIPLAY, 'mymovie.mvi', /FITSCREEN
Use the keyword SKIP to skip every n frames (good for large movies).
Example : IDL> MVIPLAY, SKIP=1 ;* to skip every other frame
Use the keyword START to start reading movie at frame n (good for large movies).
Example : IDL> MVIPLAY, START=100 ;* frame 100 becomes 1st frame of movie
Use the keyword LENGTH to specify number of frames to read in (good for large movies).
Example : IDL> MVIPLAY, START=100, LENGTH=60 ;* to load frames 100-159
Use the keyword TIMES to display date & time on frames (if not already there).
Example : IDL> MVIPLAY, /TIMES ; does not work with /DISK keyword.
Use the keyword SPEED to preset playback speed. Range is 1-100. Default is 90.
Example : IDL> MVIPLAY, SPEED=80
Calls : BREAK_FILE
Side effects: None.

Project : SOHO - LASCO/EIT
Name : WRUNMOVIE
Purpose : Widget tool to display animation sequence.
Explanation : This tool allows the user to view a series of images as
an animation sequence. The user can control the direction,
speed, and number of frames with widget controls.
Use : IDL> WRUNMOVIE [, arg1 [, NAMES=names [,SKIP=skip]]]
Use the VIDEO keyword to automatically prepare video-ready format (640x480);
use with IMG_REBIN if you want to keep full x-field
IDL> WRUNMOVIE, /VIDEO [,/IMG_REBIN]
Without any inputs, program will prompt user to select an existing .mvi file.
Example : IDL> WRUNMOVIE
Or you could have one argument, the .mvi file you want to load.
Example : IDL> WRUNMOVIE, 'mymovie.mvi'
Or if you have pre-loaded images into pixmaps (like MKMOVIE.PRO does) call:
Example : IDL> WRUNMOVIE, win_index, NAMES=names
Where win_index is an array of the window numbers and names is optionally
a STRARR() containing names of each frame.
;
Use the keyword SKIP to skip every n frames (good for large movies).
Example : IDL> WRUNMOVIE, SKIP=1 ;* to skip every other frame
Use the keyword START to start reading movie at frame n (good for large movies).
Example : IDL> WRUNMOVIE, START=100 ;* frame 100 becomes 1st frame of movie
Use the keyword LENGTH to specify number of frames to read in (good for large movies).
Example : IDL> WRUNMOVIE, START=100, LENGTH=60 ;* to load frames 100-159
Use the keyword TIMES to display detector & date & time on frames (if not already there).
Example : IDL> WRUNMOVIE, /TIMES
Use the keyword NOCAM with TIMES keyword to omit the detector from TIMES display.
Example : IDL> WRUNMOVIE, /TIMES, /NOCAM
Use the keyword COORDS to display subframe of movie images. [x1,x2,y1,y2]
Note: COORDS is applied before IMG_REBIN if both are selected.
OR just use /COORDS to select coordinates interactively
Example : IDL> WRUNMOVIE, 'mymovie.mvi', COORDS=[256,256+511,175,175+255]
Use the keyword IMG_REBIN to resize movie. If shrinking by integer factor REBIN
is used otherwise CONGRID with linear interpolation is used.
Example : IDL> WRUNMOVIE, 'mymovie.mvi', IMG_REBIN=[512,512]
Use the keyword SAVE to just save the movie and exit (for use in batch mode).
Example : IDL> WRUNMOVIE, win_index, SAVE='mymovie.mvi'
Use the keyword DIFF to subtract a base frame from all frames in the movie.
The base frame is the first frame. Or you can use the keyword START to set it.
Example : IDL> WRUNMOVIE, 'mymovie.mvi', /DIFF
Use the keyword RUNNING_DIFF to create a running difference movie.
The default is to subtract the previous frame. Use RUNNING_DIFF=2 to subtract
2 frames prior from each image.
Example : IDL> WRUNMOVIE, 'mymovie.mvi', /RUNNING_DIFF
Use the keyword /COSMIC to removie cosmic rays.
Example : IDL> WRUNMOVIE, 'mymovie.mvi', /COSMIC
Use the keyword /FIXGAPS to replace data gaps with data from previous frame
The default is to assume missing blocks are 32x32,
For 1/2 resolution images use BLOCK_SIZE=16 for example
Example : IDL> WRUNMOVIE, 'mymovie.mvi', /FIXGAPS
Use the keyword /DRAW_LIMB to draw a circle at the solar limb
Example : IDL> WRUNMOVIE, 'mymovie.mvi', /DRAW_LIMB
OTHER KEYWORDS:
LOAD Set to use saved keyword values, if any
KEEP Set to not delete pixmaps
CHSZ Set to desired size of time label (default=1.5)
SPOKE Display spoked images *** NEEDS WORK ***
DIF_MIN, DIF_MAX Set to desired range for scaling difference images; default is +/-70
RECTIFIED Set to number of degrees images rotated to put solar north up (affects header only)
/DORECTIFY Rotate frames 180 degrees
/CENRECTIFY Compute new center for 180-deg-rotation
/TRUECOLOR Set to treat images as true color images

AEE, Jan25, 2005 - Generate roll angles (using new database) when reading in frames
and keep around to use later when going back and forth between
frames (to make it quicker). The get_roll_or_xy is called for
first frame of the movie and also fo multi-day movies when a day
boundry is crossed. I added keyword ROLL_PER_FRAME to calculate
a roll for each frame if present. Otherwise, default is to calculate
one roll per day instead of one roll per frame.
AEE, Jan27, 2005 - Calculate one roll per day if wrunmoviem is called from within wrunmovie (since
movie frames are already readin without calculating rolls in wrunmovie).
AEE, Jan31, 2005 - set roll to zero when image header does not have valid date/time.

@(#)wrunmoviem_rt.pro 1.1, 11/14/01 - NRL LASCO IDL LIBRARY
Project : SOHO -LASCO/EIT
Name : XEDITFRAME
Purpose : This tool allows the user to edit a particular image "on the
fly," while the WRUNMOVIEM procedure is running, using a widget
interface.
Use : XEDITFRAME, in, out, [moviev]
Arguments : InImg - The input, or original image
FinalImg - The output, or final image
moviev - a structure generated by the WRUNMOVIE3 program,
containing information about the movie. If moviev
is not provided, then certain features of the program,
such as referencing images by "Current frame", will
not be supported.
Calls : LASCO_READFITS, POINT_FILTER, GET_FILENAME
GETSUPERBASENAME (currently included in xeditframe.pro)
Comments :
The field widgets require the user to press RETURN in order for changes
to take effect.
Much of the "overhead" in this program is for the "Undo" feature,
which necessitates extra bookkeeping.
The resulting image is = (Primary)*Normalization - (Base), which is then
clipped at saturation points (cutoffs) provided by the user.
"Super Base Frame" should probably be changed to a term easily
recognized by LASCO team members. Procedure GETSUPERBASENAME
needs to be extended significantly.
"Remove Stars" currently operates on both primage & base images
simultaneously, and only does so when the "Remove Stars" button is
pressed. For example, if primary and base images are loaded and
"remove stars" is selected, and then a different primary image is loaded,
remove stars will need to be run again -- but then the base image will
have been operated on TWICE.
On the "Primary Image" and "Base Image" buttons: If you want to
"re-select" a given button (i.e. load the original image again even
though "Original Image" is already selected), you need to click
on a different option (e.g. "None") and then click back to the selection
you want.
Side effects : XEDITFRAME disables all other widgets (e.g. WRUNMOVIEM's interface)
until it is finished.

NAME:
XPLOT_HT
PURPOSE:
This procedure is used to display height-time curves. It reads in a
height-time file created by one of the movie programs and generates
a plot.
CATEGORY:
MOVIE
CALLING SEQUENCE:
XPLOT_HT
INPUTS:
OPTIONAL INPUT PARAMETERS:
Filename: If filename is present then it is used immediately
OUTPUTS:
A plot is generated on the screen, and optionally a print file is
generated of the form idlplot.psnnn, where nnn is a sequential
number.
OPTIONAL OUTPUT PARAMETERS:
COMMON BLOCKS:
com_xplot_ht
SIDE EFFECTS:
Initiates the XMANAGER if it is not already running.
RESTRICTIONS:
PROCEDURE:
The various widgets are set up and registered. The user selects the
height-time file to be processed. The file is read in and the data
points plotted. The user is then able to fit the data to polynomial
functions of degree 1,2, or 3. The plot can be printed. The speeds
can be saved to a file.
