    keyword=RHRS detector check out with Beam

    Right HRS detector package was checked with beam. 
    
    The run used for check is run 4788, 5uA on optics target. Unfortunately,
    Q2 is down. So rates are low and momentum spectrum is different from normal.
    
    Check Results:
    
    S1&S2 TDC is generally OK
    S1&S2 ADC is OK except following problems. The gain matching is generally
    done.
    S1.chan2, pedstal is wider; 
    S1.chan3, spectrum is weird, seen on Halog 297608. 
    
    Gas Cer:
    Bad chan #6
    HV is low on chan 2, 3, 7, 8, 9
    
    VDC:
    Known problem on u2 chan 335-344, v1 chan 80, v2 chan 0-15. Raw time
    spectrum is OK.
    
    Preshower:
    Too Low HV on chan 22-24, 29, 42
    Too High HV on chan 30, 34, 40
    
    Shower:
    Missing Chan: 17-19, 21, 23, 25, 27, 30, 34, 45, 49, 51, 53, 55, 57, 59
