15.25 no merger error messages
nnaida1 & nnaida2 good events high - ~100k and ~120k respectively - see attachment 10
16.24 removed R32
System wide checks - ASIC clock timestamp test fails on all nnaidas. Synchronised clocks. ASIC clock test
passes.
FEE temperatures, leakage currents - OK
Merger reports
Merge: Restarting from timestamp 1 or greater
Merge: Starting at timestamp 27d1e55c00a0
Merge: Trying to add items to Q index 21 (Link 21) but queue already full
Probably as a result of ADC clock synchronisation.
17:03 Used analyser on R34_23. No timewarps, negligible dead time. All other values as normal.
