    keyword=possibly missing MPS on R-HRS

    We may be missing the MPS signal on the R-HRS scalers. It's probably
    been like that for a long time and ignored because R-HRS isn't important
    (?). And it probably doesn't matter as long as that's all it is.

    Evidence is that the sum of plus and minus helicity scalers does not show
    the 1.6% veto-loss for the time between helicity transitions.

    Examples of events in scalers from halog:

    Run ..... Hel + .... Hel - .... Event[0]

    20714 ... 98482 ... 97779 ... 196261 ... Note Hel+ + Hel- = Event[0]
    20713 .. 102457 .. 102421 ... 204878
    20712 .. 105507 .. 105888 ... 211395
    ...
    20698 .. 484217 .. 513240 ... 996457
