FITS Keywords

[jmorris1]

If I create master bias and darks from raw frames taken with MaxIm DL v6.08 using the ImageIntergration Process and save them in the XISF format, key FITS items are left out of the FITS header such as DATE-OBS, EXPTIME, CCD-TEMP, XBINNING, YBINNING, READOUTM, IMAGETYP, etc. 

When these masters are loaded into the BatchPreprocessing Script, they are mis-identified as to their binning and exposure times making them useable as calibration files.

I hope I don't have to manually enter all these Keywords and Values.

The easy reply is, hopefully you still have all your original images. Do the II, but save as Fits. Then you can use them in BPP. I'm sure someone much smarter than me will tell you what else can be done.

Thanks for your ideas to help but saving in FITS format doesn't help BatchPreprocessing recognize the important Keywords in the FITS header such as exposure duration, temperature, binning.

Again, hopefully smarter people than me but,,, if you create a series of folders with different exposures, binning, and temps for your master bias and darks you can load them separately as needed into BPP.
