| DCS access - offline has access only to DCS archive DB, curently no access to configuration DB | ||||||||||||||||
| DAQ - offline has access to raw data and DAQ logbook, but no acccess to LDC or GDC directly | ||||||||||||||||
| OCDB - Calibration parameters are stored in the Offline Calibration DB. The data used to calculate these parameters, the reference data, can also be optionally archived for later access from offline. | ||||||||||||||||
