CCD Calibration

[groberts]

I routinely image with a CMOS camera (ZWO ASI1600mm-Cool) and calibrate with darks, flats and bias -  recently switching to Dark Flats instead following various online advice. 

I now have some CCD data to process - having never processed CCD data I presume it's essentially the same but should I use bias or dark flats, or even both (which would seem unlikely)?

If you want to do proper calibration - one way to do it is to use darks, flats and flat darks.

Bias is useful only if you want to scale dark signal for some reason (and some CMOS sensors don't really allow for that).

Thanks vlaiv, seemed obvious but just thought I'd check.
