Check Leakage current: (see attachment 1) = 10.01 uA and falling

Check NewMerger tab: (see attachment 2)

Check Tape Server: (see attachment 3) Writing ~2500 kb/s

Check Fee temperatures: all green

Check statistics tab: ADC data items (see attachment 4)&nbsp; -aida3 and aida4 reading zero. Appears to be low noise as stat histogram shows counts as does Ey and Ex low energy histograms

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; ADC coincidence-info #8 (see attachment 5) aida1,2,5 correlation #8 signals counted. Do not see aida3 correlation 8 signals. was 70-90 previously (elog201)

Low energy histograms Ex, Ey (attachemnts 7,8)

Noise appears lower across all fees. Aida1 channels for asic 1 and 3 (noisiest) checked against elog 197, same channels are hot but at lower rate to elog 197.
