Conclusions and concerns

•The data for both TOF and T0 look good. The critical change that was made in the RHIC operation that changed the TOF from a BLM to a good detector was the reduction in background.

•It will need 1 - 2 weeks before the TOF and T0 calibration procedures are finalized, and it would be bad if DV was frozen before then. Note that none of the Au - Au calibration procedures work at the moment due to changes in triggering and changes in multiplicities.

•Can we keep time calibrator events in the PhoHit files? We need to get more experience with how to correct the data collected on the fly.
