Minutes

1. Status Update
   • There is a new CCDB release that treats 1D row-wise and column-wise tables in the same manner. Sean has verified that it works, once he found out that GetCalib() returns false when the table is correctly loaded (!).
   • Sean is doing some final sanity checks and will check in his first round of changes in the next couple days. These will depend on the new CCDB version.
   • Sean updated the Constants_to_Review page. This can serve as a list for the various groups over the summer to update based on their first data. A few old lines of code have already been taken care of. Review of the geometry classes used in reconstruction is ongoing.
2. Tracking
   • FDC alignment
   • B-field drift time correction Drift time difference due to radial field
3. Calorimetry
   • Zisis and Sean will keep in touch to develop a plan for updating the BCAL calibrations as manpower is available.
   • Eugene asked about the plan to analyze FCAL cosmic data. Matt needs to be asked about this.
4. Simulations and Calibrations
   • Work at NU is stalled due to cluster problems.
