    keyword=Pedestals Zero for ROCs 1, 2 and 4

    I noticed early and was told by Larry that pedestal suppression might be 
    off for the HRS's.  I double checked the ped files for ROC's 1-4.  
    The file ped3.dat has pedestals, but I think that is because Zhihong has
    updated them.  But ROCs 1, 2 and 4 have mostly zero pedestals for the ADC
    channels, except for channels 16-25 of ROC 2.  I am not sure what if any
    thing is plugged into those channels.
    The deadtime has been okay with the current we have been running, but the 
    lack of pedestal suppression on the right arm has to be causing higher 
    deadtime.  Also I am not sure if pedestal suppression has been implemented
    on BigBite and HAND.  If not, it would be a good idea to do so before we 
    start production.
