Minutes

Attending: Sean (NU); Simon, Beni, Kei, Nathan, Mark I., Will M., Sasha S., Elton, Will L., David L., Sergey F., Mike S. (JLab); Matt S. (IU); Curtis, Paul, Naomi (CMU); Eric (FIU); Justin (MIT)

Status Update

Activity in the CCDB has been slowing ramping up. Nathan set the tagger endpoint energy to enable the calculation of the photon energies in the tagger. Simon added some preliminary inter-detector time offsets. These depend on the trigger timing. He is going to update these numbers for the FCAL trigger today; numbers for the BCAL trigger will follow after some further analysis. Some run-dependent constants have also been added, including target conditions and FCAL gains.
