    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 558 true helicity 1 TacDecoder::ProcessStored ERROR: Numpolar 559 true helicity 0 == numpolar 560 true helicity 0 TacDecoder::ProcessStored ERROR: Numpolar 561 true helicity 1 == numpolar 562 true helicity 1 TacDecoder::ProcessStored ERROR: Numpolar 565 true helicity 0 == numpolar 566 true helicity 0 TacDecoder::ProcessStored ERROR: Numpolar 569 true helicity 1 == numpolar 570 true helicity 1 TacDecoder::ProcessStored ERROR: Numpolar 571 true helicity 0 == numpolar 572 true helicity 0 TacDecoder::ProcessStored ERROR: Numpolar 573 true helicity 1 == numpolar 574 true helicity 1 TacDecoder::ProcessStored ERROR: Numpolar 577 true helicity 0 == numpolar 578 true helicity 0 TacDecoder::ProcessStored ERROR: Numpolar 579 true helicity 1 == numpolar 580 true helicity 1 TacDecoder::ProcessStored ERROR: Numpolar 581 true helicity 0 == numpolar 582 true helicity 0 TacDecoder::ProcessStored ERROR: Numpolar 585 true helicity 1 == numpolar 586 true helicity 1 TacDecoder::ProcessStored ERROR: Numpolar 589 true helicity 0 == numpolar 590 true helicity 0 TacDecoder::End INFO: 72 pair(s) filled 0 pair(s) with missing data rejected 0 pair(s) with bad pairsynch rejected 223 pair(s) with same helicity rejected 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.
