  1. A. Sbrizzi Offline LUCID data A.Sbrizzi

  2. A. Sbrizzi Where are LUCID data? • Official reconstruction at Tier Zero: • /castor/cern.ch/grid/atlas/tzero/prod1/perm/<project-tag>/<stream>/<run>/<dataset>/<filename> • Example of 900 GeV collision data: /castor/cern.ch/grid/atlas/tzero/prod1/perm/data09_900GeV/physics_MinBias/0140541 • data09_900GeV.00140541.physics_MinBias.merge.AOD.* • data09_900GeV.00140541.physics_MinBias.merge.HIST.* (Contains hit distributions) • data09_900GeV.00140541.physics_MinBias.merge.NTUP_MUONCALIB.* • data09_900GeV.00140541.physics_MinBias.merge.NTUP_TRIG.* (Empty for the moment) • data09_900GeV.00140541.physics_MinBias.merge.NTUP_TRKVALID.* • data09_900GeV.00140541.physics_MinBias.merge.RAW (Look at them with octal dump). • data09_900GeV.00140541.physics_MinBias.merge.TAG.* • data09_900GeV.00140541.physics_MinBias.merge.TAG_COMM.* • data09_900GeV.00140541.physics_MinBias.recon.ESD.* (Contains datawords)

  3. A. Sbrizzi Content of LUCID histograms LUCID hit distributions can be found under “/FwDet/LUCID/HitMoni” KEY: TH1F hitsPmtA;1 Number of PMT hits on sideA KEY: TH1F hitsPmtC;1 Number of PMT hits on sideC KEY: TH1F hitsPmt;1 Number of PMT hits KEY: TH1F hitsFibA;1 Number of Fiber hits on sideA KEY: TH1F hitsFibC;1 Number of Fiber hits on sideC KEY: TH1F hitsFib;1 Number of Fiber hits KEY: TH1F hitsA;1 Number of hits on sideA KEY: TH1F hitsC;1 Number of hits on sideC KEY: TH1F hits;1 Number of hits The number of hits are obtained from the most significant bits of the data words. The new version will be have hits in coincidence too (under “/LUCID” rather than “/FwDet/LUCID/HitMoni”)
