Conditions

The latest updates of the CALO conditions are listed below:

Global tag Local Calo tag Description
- calo-20100426 Preliminary calibration of Ecal for 2010 data. IOV: [2010-03-15 - +inf] (patch #4040)
head-20100414 prs-20100414 New Prs gain calibration to cover the one in 'prs-20100407-calib' local tag. IOV: [2010-03-09 - +inf] (patch #4004)
head-20100407 prs-20100407-calib Prs (preliminary) calibration and gain for 2010 data. IOV: [2010-03-09 - +inf] (patch #3983)
  prs-20100407, * New condition table for Prs with numeric gains for ADC corrections per channel (needed for offline/online monitoring).
  prs-20100407-catalog * Access to this new conditions is to be implemented in a next release of DeCalorimeter. See also (patch #3958).
    * Both local tags should always come together. IOV: [0 - 2010-03-09 - +inf] (patch #3948)
  prs-20100326 Preliminary Prs calibration coefficients for 2009 data. IOV: [2009-11-22 - 2010-03-09] (patch #3947)
  calo-20100326 Preliminary Ecal calibration coefficients for 2009 data. IOV: [2009-11-22 - 2010-03-15] (patch #3946)
head-20100222 calo-20100215 New sub-folder Calo/ParticleID with the Calo PID 2D histograms is inserted. IOV: [0 - +inf] (patch #3946)
head-20100119 prs-20100117 * The Prs gain for 2009 data was a factor 2 larger than the nominal gain used so far in the software.
    * So 'EtSlope' parameter is two times reduced.
    * IOV: [2009-11-22 - +inf] (patch #3675)
