This entry is a followup to: 123467
keyword=BCM in data stream lost?To check whether the BCM information was saved in the data stream, I
added epics variables to the offline analysis script and plotted
"hac_bcm_average:g.evnum" for run 1310, 1335 and 1338. The two plots
below are for 1310 (top) and 1335 (bottom) respectively. The output
for run 1338 looks normal (similar to 1310). I suspect the BCM
information was lost from run 1331 to 1336 due to the problem reported
in entries 123467 and
123474.
If run 1331 to 1336 can be re-analyzed to include the epics and CODA
variables, then it is possible to figure out when the BCM was lost.
The BCM reading in the End_of_Run entries are, however, correct (this
is odd and beyond my poor knowledge of the DAQ).
