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. |
