    This entry is a followup to: 297234

    keyword=Compton analysis seems happier with inverted pair synch

    There is much less pairs lost and I don't see the warning message any more.

    Before change for run 20803 :

    acDecoder::ProcessStored ERROR: Numpolar 557 true helicity 1 == numpolar

    0 pair(s) with bad numpolar rejected
    0 pair(s) with no delayed helicity rejected (0 finally seen)
    0 pair(s) without 600Hz daq info kept (0 finally seen)

    72 pair tree entries
    600 polarization flip tree entries
    0 photon event tree entries
    53016 electron event tree entries
    0 coincidence tree entries
    1291 monitor tree entries
    609 beam diagnostics tree entries
    3 EPICS tree entries

    Now for run 20807 :

    TacCodaSubEvent::DecodeESubEvent WARNING: Additional unexpected electron
    subevent pattern errors, messages suppressed
    Normal end of file /home/compton/data/raw/run20807.dat encountered
    TacCodaFile::NextEvent INFO: Normal end of CODA data
    TacDecoder::End INFO:
    4028 pair(s) filled
    0 pair(s) with missing data rejected
    0 pair(s) with bad pairsynch rejected
    0 pair(s) with same helicity rejected
    0 pair(s) with bad numpolar rejected
    0 pair(s) with no delayed helicity rejected (0 finally seen)
    13 pair(s) without 600Hz daq info kept (0 finally seen)

    4028 pair tree entries
    8065 polarization flip tree entries
    0 photon event tree entries
    720265 electron event tree entries
    0 coincidence tree entries
    17912 monitor tree entries
    8007 beam diagnostics tree entries
    49 EPICS tree entries

    so I will leave the signal this way for running we will see if we get a
    photon asymmetry.
