Calibrating FITs Images

I am using a telescope in Australia that is not calibrating my FITs images with the dark, bias and flat frames. They have a serious issue that is not going to be resolved anytime soon. We are provided with the dark, bias and flat frames. I am looking for a free or inexpensive PC program that will calibrate a FITs vstar image AND output a full FITs image header with the calibrated FITs iamage, so VPhot can use the image. I tried Deep Sky Stacker but no matter what options I choose, it writes a very abbreviated FITs image header that VPhot rejects. Thanks for any adivse in advance.

I use IRIS for calibration.

You can either use a FITS editor program to add to/modify the FITS header or a script. I've written a Python script to do that. Happy to share if you want it.

I would also be intersted in

I would also be intersted in your script to edit FITS headers.

Thanks,

FITS header script

Sorry for the delay Willie.

It's here https://github.com/dbenn/photometry_tools/blob/master/modify-fits-header.py

You may only be interested in a subset of command-line options like --calstat, for setting calibration status.

Let me know if you have any questions.

There are other scripts in that git repository as well.

I would love to have a copy of your Python script

I use Python now at work. I would love to have a copy of your script(s). Please send them to me at mhotka@yahoo.com Thank you.
