Attendance: Bingchu, Xiaozhi, Zhenyu
No call from the control room last week. Time bin changed from 9 to 5 on Feb 18. 
Disabled APV 6/2/0-3, 7-11 on Feb 20. Together with the recent updates to istBuilder,
the summary plots for IST online QA become much more useful. Xiaozhi agreed
to examine these plots and the IST slow control archives on a daily basis. 
Bob Soja replied that the Pump company confirmed the new O-rings they sent
were EPDM. Bob confirmed that he would replace the O-ring in Pump 1 at the
next time when the reservoir needs to be refilled, likely in 4-5 weeks from now.
Bingchu reported his new findings with Run15 data, in particular the investigation
into max ADC Time Bin=0 hits, after offline reconstruction. A clear correlation is 
observed between the number of IST hits with TB>0 and number of TOF matched 
tracks, while no correlation is seen between the number of IST hits with TB=0 and 
number of TOF matched tracks. He will make additional plots and comparing
begin-/end-of fill runs to further understand what is going on.
