  1. MC/OFFLINE meeting LNF 31 Jan 08 Status of MC - G. Venanzoni aob

  2. News: All_phys production finished!Statistics of 2004/05 ~doubled (ref ~ 1.75 fb-1)

  3. From 8 Jan 08 Status of MC After completing the all production (all_phys) for 2004/05 (1.75 fb-1) at LSF=1, we had the request (before the summer 07) to duplicate the MC all_phys statistics (mainly for ke2 analysis): We decided to do two sub-productions (all_phys2 and all_phys3) @LSF=0.5 each All the productions have mccard_id=2, but can be distinguished by: dtr_gb_nr=0 for all_phys (LSF=1) dtr_gb_nr=1 for all_phys2 (LSF=0.5) dtr_gb_nr=2 for all_phys3 (LSF-0.5) example (for all_phys2): kls mcdst “run_nr=34472 and mc_mccard_id=2 and dtr_gb_nr=1” (if you don’t specify dtr_gb_nr, all_phys+all_phys2+all_phys3 are selected) The production all_phys2 is finished, while we are now finishing all_phys3. The initial rate was ~13 pb-1@LSF=1 on 128 slots, changing to ~18 pb-1 after a modification to datarec (in “get_mc_version” routine) Other issues: Mcr files are “physically” deleted (but not the entries in the DB) krare production for 2004 has benn also done mrc dst of 2005 with correct +-e+e- completed

  4. At 31 Jan08 All_phys MC production News: More failures in all_phys3 than in all_phys2 (~60 pb-1) .

  5. Why more failures? We are investigating…

  6. Short term plans After the Shutdown of the next week we will restart the offline activity with the Reprocessing of 2005 data with DBV<25: ~80 days (1.1 fb-1) Reprocessing of 2006 data (with new  selection): 2 weeks ? Dst’s holes Rad MC LSF = 5: ~10 days ? Beltrame’s request: 250pb-1 of Bhabha at 1 GeV (~1 week) Tommaso request: Bhabha 2004/05, EFF=~600nb

  7. Status of reconstruction trgmon luminosity in pb-1 by year and DBV Don’t have +-e+e-selection. We want to reprocess them OK We want to reprocess 2005 data with DBV<25 (~1.1. fb-1)
