    keyword=Added TDC to ROC 4 in Slot 9 for Trigger Signals

    Prior to today, I had only T3 and T5 going into a TDC on the left HRS.
    The problem was that the triggers that Kalyan was sending up to the HRS
    were too delayed to add to the multi-hit TDC (1877). To get around this
    issue, I added a 1877 into ROC 4, Slot 9. For this TDC, I created a gate
    that was delayed with respect to the triggers coming back to the HRS.
    This way I have not affected the gates for any of the other ADCs or TDCs.

    I then plugged the trigger signals into channels 48-63 of the 1877 in
    slot 9. I modified the crl code for ROC 4 to readout slot 9. My first
    test of this seems to have worked well.
    I added the new variables to the analyzer DecData class. Here are the
    channels:
    # trigger input LHRS copy in 1877
