Most important DB folders for HCAL analyses

Other necessary or useful conditions data path can be found here: other conditions data

HCAL geometry

In total, four DB folders are needed to describe the Hcal geometry:

  /cd_calice_cernbeam/Hcal/HcalModuleDescription   - Module layout
  /cd_calice_cernbeam/Hcal/HcalModuleLocationn     - Module position in stack
  /cd_calice_cernbeam/Hcal/HcalMapping             - Module connection to DAQ
  /cd_calice_cernbeam/Hcal/DetectorPosition        - Stack position for 2006
  /cd_calice_cernbeam/Hcal/HcalDetectorPosition    - Same for 2007 

HcalMapping

Pedestal subtraction

There is no run-to-run pedestal available in the database, yet. For the moment, it is recommended to use the PedestalOnTheFlyProcessor.

Calibration

The IntegratedHcalCalibrationProcessor is designed to apply Mip calibration, zero suppression and non-linearity correction. These folders need to be invoked in the ConditionsProcessor:

  DBCondHandler SiPmInfo             /cd_calice/Hcal/ITEP_DB         HEAD
  DBCondHandler SiPmSaturation       /cd_calice/Hcal/ITEP_Saturation HEAD
  DBCondHandler SiPmModuleProduction /cd_calice/Hcal/Production_DB   HEAD

Further, calibration constants are needed for each half-module. Average calibrations for 2006 (broken up in two periods for August and the stable half of October) and 2007 are in folders

  /cd_calice/Hcal/Gain/Approved
  /cd_calice/Hcal/MIP/Approved
  /cd_calice/Hcal/Inter/Approved

All calibration measurements for 2006 are archived in these folders, stored with validity times equal to the time interval of the data (e.g. an ahcGain run):

  /cd_calice/Hcal/Gain/Inofficial
  /cd_calice/Hcal/MIP/Inofficial
  /cd_calice/Hcal/Inter/Inofficial
