• example MINI kumac for ARTE-04-01-r5
• The 1st Note for the 3rd reprocessing applies.
• The dimuon soft MINI selection of events with (bit #2 && mass > 2 GeV) can be found in     /hb/select2/data/selection/jpsimm/
  here is the MINI selection statistics.
• There is also a dimuon DST preselection (bit #24 (ECLASS_JPSIMMH)) for the MUON masking studies (/acs/user3/dima/rp5-jpsimmh-raw). Its reconstruction a la repro 5 with MUON HITB included into DST is located for 2002 in /acs/test/data/REAL/04/exp04/*/run22002/rp0101_* and /acs/user3/dima/rp5-jpsimmh-mini/ and   /hb/select2/data/selection/jpsimmh/  , and for 2003 in /acs/test/data/REAL/04/exp04/*/run22003/rp0102_*     here are the two tables with statistics for the 2002 hard selection and 2003 hard selection.
• The number of reconstructed events in the triggered runs often is significantly smaller than the total number of events, most of this difference comes from the cut on OTR number of hits <13 k. This cut was introduced to make the Arte processes behave on the farm and speed up the reconstruction; it is assumed to be harmless since the standard J/Psi selections use a cut of 10 k OTR hits.

• A substantial part of rp0005 statistics may be not accessible due to broken tapes, for MinBias one can use repro 6, while the affected dilepton-triggered data has been re-reprocessed as repro 502.

Reprocessing 2002/2003 runs No. 3

• Keybook 27, ARTE-04-01-r3
• Runs: 19886-20921, 21122-21304
Note: For the runs 20922-21121 the reprocessing 3 was not necessary. They are available as repro 0 with the same reconstruction quality as the other runs.

        IOFILE DST_IN_EDIR /afs/desy.de/group/hera-b/DATAMGR/.rp0003_RunCatalog -IG
• There exist a dimuon selection for the whole data taking period 2002/2003. Add in your kumac:

      IOFILE MINI_IN_NOTE /hb/select6/data/SELECT/03/exp04/jpsi/mini/JPsimm.nbx -GI
• example MINI kumac
for ARTE-04-01-r5 from bbbar group
• Note: The DST files contain only around 5% of all the events and all the events in the classes #1 (J/Psi->ee) and #2 (J/Psi->mumu). This fraction is considered to be enough for reconstruction studies. The classification bit #23 has been created to allow direct access to the events with full DST information. When reading DST events, please use in the kumac:
SELECT 'run=runnumber and class=#23'
