We frequently need a way to quantitatively compare images, mostly calibration images, spanning various events or covering time ranges. I have developed a code that does this for LRS2.
% process_lrs2_images_step1 --help Usage: process_lrs2_images_step1 list.Qth Y N arg1 - Name of file with list of raw LRS2images (should be full path) arg2 - Use ds9 to set statistics box? (Y/N) arg3 - run in debug mode (Y/N) A handy code for locating LRS2 calibration frames" % lrs2_lglist Usage: lrs2_lglist Y arg1 = Run in debug/verbose mode (Y/N) See examples in: /home/sco/LRS2_Nov15_Tests/S/README.LRS2_Nov15_2018_Tests /home/sco/LRS2_Nov15_Tests/run2Both of the above codes are still being developed. Because they are likely to change significantly I will not write a lot of documentation now. This is just a place-hold to remember that they exist. Since it has a lot of good examples, I include the early source code for process_lrs2_images_step1 here.
