    keyword=RICH runs summary and test

    Had trouble with the pedestal configuration of sync, will have to fix that.
    Use TWOARMRich for pedestal run 2912,2913,2914
    took one run without pedestal subtraction with T1 only
    Dedicated RICH run 2916 and 2917
    One run with RICH with mixed trigger T1,T3 and T5 run 2918

    With the condition on TH and putting a limit on the number of channel read by ADC reduced the dead time but still too high. Still a problem that RICH dead time is significant with other triggers.
    One ADC in ROC15 puts the same channel in the data stream several time, will have to check if it is a problem of clearing or a hardware problem.

    Will look at the data to figure out the problems. Most likely will spend a day at beginning of 5 pass to improve/solve the problems.
