    keyword=L-arm TC time change

    In order to make the L-arm measurement of coinc. time ("ctimel")
    show up near the middle of the TDC dynamic range, I had to add
    80 nsec to the stop (?!?!). The time diff (stop-start) is 254 nsec
    as measured on a scope. But this is an unsettling result since
    80 nsec is a HUGE change. Makes me wonder if the pulser is not
    set up properly or ... what. Make sure you check that other timings
    did not change much, e.g. VDC T0 and scintillator offsets.
