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

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.
