  1. New calibration strategy – follow-up from the production review ALICE Offline 07/02/2011

  2. GSI proposal Slide courtesy of Silvia Masciocchi

  3. Assumptions • Weekly AliRoot updates (Rev + AN tag) • All PWGx + AOD filtering trains run in synch • Weekly OCDB updates (in addition to Pass0) • n=4 calibration passes until ready for Pass2 • period length = 4 weeks • Reconstructed sample = 10% of full sample • If period + calibration passes not sufficient, the shema can be extended

  4. Calibration passes – one period CPass #1 CPass #2 End of period Ready for Pass #2 CPass #3 Cpass #4 (full 10% cycle) CPass #5 (full 10% cycle) CPass #6 (full 10% cycle) CPass #7 (full 10% cycle) 1 2 3 4 5 6 7 Week #

  5. Repartition of Cpass #x PWG2 Analysis train AOD train + tender PWG3 Analysis train Pass0 reco Pass0 Calib train + OCDB update Cpass #x reco PWG4 Analysis train PWG1 QA train Muon AOD train • In total: • 2 reco passes • 2 calib train passes • 6 PWG+AOD trains Ready Cpass #x Calib train + OCDB update Not automatic TBD

  6. Summary of period pass • Total data volume – 55% of RAW • Calibration (post Cpass #x) to be discussed • What will be updated here? • What is the required ouptut of CPass #x to allow for calibration • Which detectors can join • AOD and PWG#2, 3, 4 trains must run at the same time • Strict discipline in the train code
