I thought that I corrected for different ranges of pramp, pulse and threshold DACs
between ABCD and ABC but I didn't so the measuerments are taken at somewhat
strange values of charges and preamp currents.

* Preamp was set to DAC = 6 (150uA)

* Threshold scans were done at different charges (strobe delya was optimized
    but same value was used for all the charges)

* Vcc = 3.5V ,Vdd = 4V
    Currents measured at Preamp DAC =  11: Ianalogue = 0.39A and Idig = 0.16A

Here are some plots:

An example of threshold scan:

 
Example of response:

Gain at 0.93fC accross the hybrid:

Noise at 0.93fC across the hybrid:

50% points acros the hybrid:

Threshold Spreads for Chip 0 at 0.93fC:

Average gain for chip 0 is 143.5 units/fC and average RMS from the above plots is
2.1. The threhold spread is then 0.015fC (at 0.93fC).
