    keyword=testing bpm signal with slow raster shape

    Trent,Alexandre and I tried to change bpm setting to see if there have any improvement for bpm signal.
    for run 4097 and 23091 is in 100nA
    then we increase the gain for run 4099,23093, BPMB looks better
    then we increase the gain again for run 4100,23094, BPMB signal worse
    then we change current to 50nA, and change the gain, the run is 4101,23095
    then we change current to 25nA,run is 4103,23097,both bpm looks bad
