D. Adams
June 2008

Release 14.2.0 is development.

For other releases, see the complete list of results.

For a summary showing successes and failures in running MuonRecRTT, see the MuonRecRTT summary table. Metrics and links to performance plots for selected RTT jobs may be found below.

Issues in 14.2.0 development

1. Hole counts are absent for muid and staco combined.
  • Hole counting is not enabled in 14.0.X reconstruction.

    2. Muid combined fit chi-square does not include the inner track. Staco includes inner, outer and match.
  • Users should add Muid inner and combined chi-squares (and DOF's) to get comparable values.
  • This is a feature, rather than a bug.

    3. Calorimeter-tagged muons all have energy loss set to zero.
  • Feature?
  • Same in 14.0.0.2.

    4. Reco 14.1.0.1 from bytestream produced with 13.0.40.5 has inefficiencies.
  • Muon bug report 36729.
  • D. Adams talk at May 23 physics validation.
  • Not yet (02jun) confirmed or denied.

    5. MuGirl has low efficiency for eta>2.0 and eta near 1.2.
  • Problem seen in 26may build.
  • Efficiency worse in 29may and 01jun builds.
