As every astronomer that deals with optical images will know, IRAF can be a real bitch sometimes. Although IRAF is very useful once you know it, it is also known to be a time vampire when doing astronomical image reduction. But is there really an alternative to pre-pharaoh xgterm reduction procedures? YES there is! In comes THELI. THELI is an astronomical image reduction program which automates the image reduction procedure. Now there are two versions of the program, but if you are like me and you just quickly want to reduce the .fits files you’ll want to go for the GUI version (point and click version).
The GUI version let’s you reduce your image data fast and easy for a whole range of preconfigured instruments. If you have not given the program a try I suggest you do. To get the free program go here.
If you have had any experiences with THELI I would love to hear about them. Please comment below.
Hi Paul!
My name is Artem and I absolutely agree with you. For me WCS setting in IRAF is the most difficult because of features of the telescope I use. But for hundreds of images IRAF is the only thing.
I’ve never heard about THELI, but I’ll try it. Thanks for short review.
