Hello Carlos,
Thanks for the neat module.
I tried to apply it the master bias of by Canon 1000D camera.
I took 84 bias frames, debayered and integrated them. An STF showed a color image. But the SuperBias frame is Monochrome.
Is it the expected result? Or should I separate the channels and then apply SuperBias?

Thanks and Regards,
Keerthi

You should not debayer raw frames for calibration. Only light frameas are debayered, after calibration, before registration and integration.

Thanks Carlos... That makes sense.

Carlos,

Really like this SuperBias. I tried it on 50 bias frames from a Canon 1100D at ISO 400. The original master bias has significant vertical banding. What is interesting is I tried running SuperBias and changed the Data Extraction Parameters. I ran one at default or "7", then one at "5", then one at "9". Obviously the results differ, notably in the signal information at the top of the image (it looked like amp glow in the original). What is the significance of these numbers? What might I want to see in the finished SuperBias image? Thanks.
