Pass7 todos

This is the list of desired udpates to complete before the Pass7 merit reprocessing (currently targeted for early february)

Recon udpates

• saturated ToT bug fix (Leon) - available from GR ?
• energy unbiasing (Michael,Tracy, Leon working on GlastReleasing Carmelo's root macro

Additional merit variables

• Overlay related
  • Run and event number of the overlay event
  • input overlay event trigger bits
  • number of ACD tiles hit and the energy deposited in them
  • number of CAL crystals hit and the energy in them
  • number of TKR hits
  • Fix to some existing ACD variables. Energy and tile count should be cut on ACD accept bit. This will not affect normal data, which implicitly has this cut. But the tiles in PT events are not zero-suppressed, so we currently get funny numbers when we make "Gleam-skim" PT events.

• Mc related, to be added in the McTH tool
  • Number of daughters of the primary particle
  • Process that created the daughter particle (currently two daughters, this is a string)
    • We might also look at restructing how the daughters are handled...  right now "daughter1" is really the "best" daughter meaning the one  that produces the most McPositionHits. But we might want to change to  straight order so that if an incident gamma compton scatters first  then we have the compton electorn as the first daughter.
  • Position of the creation point of the daughter (currently two)
  • Initial direction of the daughter (four momentum? curren tly two)
  • Number of McIntegratingHits associated to the primary particle
  • Energy deposited due to McIntegratingHits associated to primary

• cluster tagging variables (e.g. TkrNumWideClusters) - use GR > v15r53p2.  Done
• ToT255 bug fix (Leon) - GR ?  Done
• Lambda magnetic coordinate (JFO definition) - needs implementation in GR  Done
  • Ditto: signing PtMagLat and adding R and B field components  Done
• Deadtime - needs definition and implementation in GR  Done
• Rocking angle (JFO+Seth definition) - needs implementation in GR, will be non-backward compatible  Done

Worksheet

• proton and HI cuts - need defs from Markus, Simona, Maria-Elena need; Carmelo to implement in worksheet
• separate vetos for P6 leakages - Carmelo to add HI veto from Simona and low energy CAL evts from Riccardo
• consistent definitions of CTBParticleType and CTBClassLevel over all worksheet

Sundry items

• physics trigger cuts in IRF
• Should we use Hiro's new TKR gain constants for Pass7? (and does this imply that we should also use them for generating the PT overlay events now?)
