The file with the background array, bkgd_fname, was obtained by averaging 1000 events using module CSPadArrAverage. Subtraction is done with normalization for norm_sector=0.
Event image and pixel amplitude spectrum before and after the background subtraction are shown in plots:
Other event with better subtracted background:
Events at the end of the run:
As a cross check, the averaged over the same 1000 events array with subtracted background is shown below.
As expected, it is about zero.
