Issue with biased pedestals

Browser images using command

.../psana/detector/test_01_epix10ka_raw_calib_image.py image -e ueddaq02 -d epixquad -r168 -Sraw-peds -J1

which plots epixquad images for raw - pedestals

99% and 1% images:

Both type of images can be passed by the gated average algorithm..., but second type gives significant offset to the average value and increases rms.
