    keyword=L-arm RT problems, HV problem

    The HV on L-arm S1-5L is not engaging. I'll try to fix it.

    I noticed a problem with L-arm RT. There were jumps by 50 nsec
    and 22 nsec relative to L1A. After tracing this down I found
    it was due to some delays added to the INPUT of the discriminator
    for S1 PMTs. I think this was done for TDC dynamic range issues
    but it causes problems for the trigger. Normally we want all
    PMTs to be aligned in time. Will try to fix it.
