How to evaluate the noise of fits image?

[LKHZ]

Hello, I'm going to evaluate some of my fit images. I read your BANE documents, but I still don't know how to use them. Can you give me some suggestions? Thank you.

Hi,

Once you install AegeanTools you should have a new command line tools available called BANE. You can run it like this:

BANE my_image.fits

and it will create files my_image_bkg.fits and my_image_rms.fits which are the background and noise maps.

See https://github.com/PaulHancock/Aegean/wiki/BANE for more detailed description on how BANE works and how to use it.

Paul.

Thank you very much for your reply. In the way you said, I successfully ran the program and generated the background image.
