Exact Steps BatchPreProcessing Script Takes...?

[jimwaters]

Does anybody know the exact steps the BPP Script takes?  Is this documented anywhere?  Thx

Jim,

I don't know of any documentation with exact and up to date details.  You can get some of this from the parameters in the script dialogs and process console output.  For the rest you'd probably need to read the source code.

Cheers,
Rick.

What I am trying to find out if just Flats are normalized against BIAS or both Flats and Darks are done from a DSLR standpoint.

if you look at one of the calibrated flat subs, the fits header should show the ImageCalibration history including what types of calibration frames were applied and what the calibration filenames were.

Rob - Thanks.  It only looks like Flats are calibrated when using BPP.

Some on the internet say both Flats and Darks should be calibrated. They didn't make a distinction between DSLR, OSC or Mono CMOS / CCD.

BPP creates a master dark that isn't bias calibrated but can calibrate the master dark with the master bias on the fly when calibrating light frames (see the Calibrate box under Master Dark in the ImageCalibration dialog.

Just saw it a few minutes ago.  Many thanks.
