This is a bash script that uses a lot of other tasks (some sco, some others) that takes two images as input on the command line. Both images are assumed to have a valid wcs. The second image is presumed to be displayed in a ds9 window. The purpose of the task wcs_outline is to draw in the outline of the firts image. Also, the corner for pixel 1,1 is indicated with a small circle.
% % wcs_outline a.fits dss.fits arg1 - name of input FITS image with WCS arg2 - name of input FITS image for displayThere is a fairly complete sample run of this in $tdata/T_runs/wcs_outline/ex0_n7790.
