Fall 2014 Data Calibration Status

This table summarizes the status of the calibrations that have been stored in the CCDB.

Last Updated -- 9 Feb. 2015

  • red - This category has not been calibrated
  • yellow - Calibrations have been partially done, or done with cosmic ray or other non-photon beam data
  • green - Calibrations have been done with photon beam data


Detector Base Time fADC E scale fADC gains fADC timing TDC timing TDC timewalk Low-level reco. obj. High-level reco. obj. Alignment
BCAL N/A 1 1
CDC N/A N/A
FCAL 1 N/A N/A
FDC N/A N/A

TAGH 1 1
TAGM 1 1
TOF 1

Notes:

  • "Base time" refers to the relative timing between different detectors.
  • The fADC and TDC categories refer to per-channel calibrations.
  • The high-level reconstruction objects are the final inputs to a physics analysis. The low-level reconstruction objects are whatever objects are built from the calibrated hits and used to build the high-level objects.
