NAME:
DIFBKGND
PURPOSE:
Difference the appropriate background image
CATEGORY:
DATA_ANAL
CALLING SEQUENCE:
Result = DIFBKGND(Img,Hdr)
INPUTS:
Img = Input Image array. It is assumed that the array is full image,
(either 1024x1024 or 512x512) so that if the original image was
a subimage, it must be put into the proper place in a full image
array.
Hdr = FITS header
KEYWORDS:
MINVAL: If set, the minimum value for the byte scaling is set to
this value. The default is the minimum value in the image.
MAXVAL: If set, the maximum value for the byte scaling is set to
this value. The default is the maximum value in the image.
LOGSCL: If set, a logarithmic scaling is applied. The default is
linear scaling.
ALTMIN: If set, the minimum value for the byte scaling when the
background image is NOT found is set to this value. The
default is the minimum value in the image.
ALTMAX: If set, the maximum value for the byte scaling when the
background image is NOT found is set to this value. The
default is the maximum value in the image.
ALTLOG: If set, a logarithmic scaling is applied when the background
image is NOT found. The default is linear scaling.
RATIO: If set the input image is divided by the model. Zeroes in
the model or input are set to 1. The default is to perform
a subtraction.
NO_SCALE:If set the output image is not byte scaled. The default is
to byte scale the image.
OUTPUTS:
The function returns a byte scaled difference image.
PROCEDURE:
The input header is examined to extract the telescope, filter and
polarizer/sector. The directory pointed to by the environment
variable $MONTHLY_IMAGES is searched for all monthly images that
exist for that combination. If only one monthly image is found it
is used. Otherwise the monthly image whose Mid-Date is closest to
the date of the input image is used.
No background subtraction is performed if the input image is a dark,
cal lamp, and continuous mode. In these cases the image is byte
scaled using histogram equalization. If the image is not 1024x1024.
or 512x512 then no background subtraction is used, but the image is
scaled according to the input keywords.
