General

The p20.16 d0reco is for reconstructing new data taken after 2009 shutdown.

Status

p20.16.01 was frozen on August 24, 2009.

- p20.16.01 certification plots

  • comparing p20.16.01 performance with p20.12.05d :
    • The black is p20.12.05d.
    • The red is p20.16.01.
  • comparing p20.16.01 performance with p20.16.00 :
    • The black is p20.16.00.
    • The red is p20.16.01.

p20.16.00 was built on August 18, 2009.
- p20.16.00 certification plots

  • comparing p20.16.00 performance with p20.12.05c :
    • The black is p20.12.05c.
    • The red is p20.16.00.

The code differences between p20.16.01 and p20.16.00:
  • added fake track killer package

The code differences between p20.16.00 and p20.12.05:

  • Changes in tracking:
    • New alignment
    • CFT fiber level cuts.
      Maximum time cut vs. PE (remove 1% of hits on good tracks).
    • Calculate CFT time parameter.
    • adding an attribute to ChargedParticle class.
    • Run GtrMissPkg and Fake Track Killer (FTK) inside d0reco.
    • adding misses to tracks, but the chunks and objects don't change.
  • Muon changes:
    • Additional protection of the muon hit (PDT, MDT) indices is installed to avoid possible errors in electronics.
    • Changes c-layer t cut from 10 to 13 ns.
    • Changes nseg3medium.
    • Fixes isolation bug.
    • Crash fix.
  • Calorimeter and ICD changes (NOT in p20.16.00 yet):
    • New ICD calibration. Changes are in databases. No code changes.
    • We may have calorimeter calibration updates. Changes are in databases, no code changes.
