    keyword=helicity signals

    To test the spectrometer helicity signals, and whether spectrometers and Moller
    use the same convention, we put alternate signals downstairs
    into the spectrometer DAQ. This starts after 176 k events in run 1510.
    Runs 1511 - 1515 are dedicated to this. In run 1515, we make the signal
    going downstairs ~3/4 ``h+'' and ~1/4 ``h-'', and see that we correctly identify
    the nominal signals in the espace replay. A Moller check needs to be done.
    The online replay spectrum is below.
