QuickLook Main Routines
		       -----------------------

This directory holds the bulk of the active routines in the
CDS QL Display programs. 


			  Reading FITS files

Reading FITS files into IDL for use with the QL routines is done
with READCDSFITS (or READCALFITS for calibration files):

IDL> a = readcdsfits('testdata.fits')

In order to specify the directory, the routine CONCAT_DIR may be
used, e.g.:

IDL> a = readcdsfits(concat_dir('$CDS_NIS','testdata.fits'))

Then I would suggest calling DSP_MENU,A to see what's available.
Note that in DSPSPEC/DSPEXP you select the function of the mouse
cursor by a pulldown menu.

Calibration files should be read by READCALFITS instead of
READCDSFITS.
