Detailed Description

The CrossSection class This class stores a yield tree... stored as (particle, tagger channel) pair Yield tree has: is MC = marker for MC data = data string, could be decay from MC, or setup, user specified sp_X = kinematics for scattered particle tc_X = parameters for tagger channel missing_mass = missing mass (ignoring recoil)

Note: prompt random fill weight is stored as tc_promptrandom Yield->Draw("missing_mass","tc_promptrandom") produces pr-subtracted missing mass

Also stores scaler tree: tagger_channel = dummy vector of tagger channel tagger_scalers = vector of scalers tagger_eff = vector of tagging efficiency tagger_deff = vector of tagging efficiency errors exp_livetime = experimental livetime

Scalers->Draw("tagger_eff:tagger_channel") produces 2d tagg eff vs. tagger channel plot Scalers->Draw("tagger_eff[30]") produces 1d tagg eff values for channel 30

USE:

Once per event:

 cross_section.SetEventType(event.Reconstructed().ID.isSet(ant::TID::Flags_t::MC), decay);
 Note: this will also track incident flux

After all cuts,loop over tagger channels:

  for (const auto &tc : event.Reconstructed().TaggerHits){
     promptrandom.SetTaggerHit(tc.Time);
     cross_section.AcceptEvent(Meson,Meson_time,tc,promptrandom);
  }
