Comparison of RICH digitizer parameter (SEP08)

In this report different RICH digitizer parameters are compared for electrons using one embedded DST file from SEP08 (be08271001914_geant_em1.root). This was done in order to understand the differences in APR07 and SEP08 efficiency matrices. The studies were done first integrated over all sectors and then differential for the different sectors (with and w/o track cuts (innerChi2 > -1 && angleToFittedLepton >9 && angleToNonFittedLepton > 9)). For all studies the efficiencies are shown vs. Theta and vs. GEANT momentum (for TOF and TOFino region).

The different RICH digitizer parameters are:
  • SEP08_gen1a: SEP08 parameters before adjustment (RICH digitizer adjustment JAN04-SEP08).
  • SEP08_gen1b: SEP08 parameters after adjustment.
  • APR07_gen2: APR07 parameters after adjustment.
  • SEP08_3sigma: like SEP08_gen1b but with 3 sigma instead of 2 sigma cuts.
