Notes: * Handover at 00:31 because MWV is a softie. (middle of night was 00:28). * Pyraf really is Python, so the following snippet is useful to look at the last image minus the previous image just cut and paste the following into the Pyraf terminal def compare(im1, im2, imtmp="../mwv.fits"): iraf.imdelete(imtmp) iraf.imarith(im1, "-", im2, imtmp) iraf.display(imtmp,2) iraf.imexam() def check(objnum): im1="obj_%03d" % (objnum ) im2="obj_%03d" % (objnum-1) compare(im1, im2) And then you can run --> compare("obj_030.fits","obj_029.fits") to do * subtraction of the two files * display them to ds9 (frame 2) * launch imexam For convenience, 'check' takes an obsnumber and automatically 'compares' against the previous one. E.g., the following are equivalent: --> check(30) --> compare("obj_030.fits","obj_029.fits") I ouldn't figure out the PYTHONPATH or such for the Pyraf, so a civilized "from compare import *" for the file named compare.py in the observer@dust home directory didn't work. MWV is a bit embarrased it took him several years to think of doing this.
