Using a masterdark in BPP script

[cdavid]

Hi...I have various master darks in my library which I previously created the old manual way  (integration after master bias calibration). I also used to make a version without master bias calibration.

So in the BPP script which should I use....does the script detect master darks that have been bias calibrated or will it subtract the bias again?

Thanks!

Anyone know? Thanks

I don't think it does. I only use BBP for bayer drizzle processing, and since I typically work with uncalibrated master darks with my DSLR cameras (to avoid data truncation), I subtract the master bias prior to feeding it to BPP.

Thanks Ignacio....so you mean that you calibrate your master dark using the calibrate process prior to BPP?

Do you also give BPP a master bias to calibrate flat and lights?

Hi Carlos, this video can help.

Saludos, Alejandro.

Thanks Alejandro! Perfect just what I needed to know. I've been using bias calibrated master darks  in the BPP which explains some errors and artifacts I've been seeing.

Cheers!
