Comtinued Cherenkov threshold scan at both 1300 and 1300+10% voltage
settings.
Readjusted the DC offsets (to bring them back to zero) for the
Cherenkovs, which had drifted since last night:
adjustment:
--------------------
RC0 +2.4 mV
RC1 +0.4 mV
RC2 +2.8 mV
RC3 +2.2 mV
LC0 +0.5 mV
LC1 +1.2 mV
LC2 +1.2 mV
LC3 +1.0 mV
Took about 750kEvents for each threshold
setting: (elastic_coincs.settings
NC_CC_1300.sql
setting runs
----------------------------
35 mV 2749-2753
45 mV 2754-2758
NC_CC_1300_10percent.sql
15 mV 2763 (only 140 kEvents)
25 mV 2761-2762
35 mV 2759-2760
45 mV 2757-2758
beam and coda were good all night except had to restart CODA once.
