set of response curves for 68 channels resp.ch700-768.ps,
Timing scan of one chip in an attempt to look at pulse shape.
Iinput = 9 counts (82.8uA) Ishape = 9 counts (9.8uA) cal size 48 counts (6fC)
The bottom axis is reversed in time and is from 1-63 in steps of 2 of the on chip calibrate timing delay register. The vertical axis is the value of threshold at which >20% efficiency was first detected after scanning DOWN with decreasing threshold from vthresh = 200 counts . ts.ch1-128.ic9.ps,
