Final step is to check the calirbation of the light.
First I remove the flats and bias from the file list
at 1)LOAD, i click on the “ALL” switchbox to the right of the flat/bias button. This deselects the flats/bias frames. Then I click on “clean” to the right of the swithchbox. All bias and flat frames are now removed from the file list.
I then add the BPM and the light frame.
I load the light frame linearly which is the first image,
and secondly with l-calibrated to verify calibration. Result looks good to me ;-)
André, possibly, the error in calibration that you had, had to do with the flats not being bias calibrated?
