SIngle angular bin still works fine in our ROI defined by both masks.
Background subtraction examples
Subtract background shape evaluated in run 192
Radial background subtraction
Image corrected up to 80mm, 40<phi< 320:
Image corrected up to 80mm, rings span for entire phi
OLD IMAGE PROCESSING
Subtract background shape evaluated in run 192.
