After checking the shifts in gain, it seems that for most of the detectors the dynode and anode signal moved in the same direction with the exception of detector 13 (dynode and anode do not move

equally, so probably there is a cable problem here, probably in the Dynode 13 or preamp problem)

The low energy channels of AIDA have been gain matched. Attached is the energy plot of the x and y side strops in AIDA.
