    keyword=Please check Quad polarities !

    On the way home I remembered that a prime reason for getting low
    rate in the HRS is if one or more Quad polarities is flipped.
    It should be checked by an expert, e.g. Alexander.
    This could explain why the R-HRS rate is ~25 times lower than L-HRS,
    for both the Parity DAQ and the scintillator trigger, although the
    momentum distribution looks about right (perhaps 1 cm misaligned).
    Other candidates :
    1. Massive misalignment, but doesn't make sense since also T5 is off.
    2. Something physically blocking, but this doesn't make much sense.
    3. Something bizarre happened with dipole repear (?????)
