    keyword=S2m L-HRS fixed itself?

    It appears that the timing of the common start for the TDC shifted spontaneously again, as was seen during Hypernuclear and the Pentaquark experiments, however this time the shift was much larger. After power-cycling the FASTBUS crate, the TDC has fixed itself.

    This is a LeCroy 1875A TDC, and this board has a history of doing this. Unfortunately, we have no spare 1875 boards. If this happens again, we might have to move S2 back into the lower-resolution 1875 that S1 is using.
