Hi, Chi (or anybody with two minutes)!
What is the 3000 value in TBLEvent we seem to use consistently to define
beam helicity, target spin state etc.?

  fSpinBits = SpinBit((recon.fRaw->GetSHtgtstate1() < 3000) ? 1 : 0,
                      (recon.fRaw->GetSHtgtstate2() < 3000) ? 1 : 0,
                      (recon.fRaw->GetSHtgtstate3() < 3000) ? 1 : 0,
                      (recon.fRaw->GetSHtgtstate4() < 3000) ? 1 : 0,
                      (recon.fRaw->GetSHtgtstate5() < 3000) ? 1 : 0,
                      (recon.fRaw->GetSHtgtstate6() < 3000) ? 1 : 0,
                      (recon.fRaw->GetSHtgtdef() < 3000)? 1 : 0);
  fBeamHel = (recon.fRaw->GetSHbeamhel() < 3000) ? 1 : -1;
  fBeamFlip = (recon.fRaw->GetSHhelflip() < 3000) ? -1 : 1;

Thanks!

Adrian
