Comparison to v14r2 shows differences in the ACD digis. Examples shown below – this seems to reflect Eric's fix to handling pulses below the zero suppression threshold.
The comparison is made to v14r2 instead of v14r3, which was interrupted mid-build by the weekend computing outage.
All of the system tests (except the vertical muons) show a similar change in the ACD digi ADC plots. You can see increase in zeros and suppression of sub-zero suppression threshold pulses. (Shown below for the AllGamma test.) Note that in v14r4 the low count shoulder disappears.
In some cases the ribbon MIPs plot has changed in a similar manner (AllGamma shown).
The VerticalGamma100MeV test shows a difference in the ACD digi total sum (below). This also appears consistent with setting sub-threshold PHA's to zero.
