Review of minutes from the last meeting

We looked at the [[???|minutes from the last meeting]. Elliott remarked that in the translation tables there was no need to identify the pre-amps for the tracking chambers as separate entities.

Status of the CCDB release

Dimitry is finishing the conversion from existing Subversion-controlled calibration constant files to the CCDB

  • built JANA, put in classes to read CCDB
  • getting ready to test
  • should be done in the next few days
  • CCDB has been checked into the 12 GeV Physics repository

Elliott commented that some progress on the conditions part of the CCDB would be useful.

Update on non-deterministic event reconstruction

David has found and fixed a problem, first reported by Will, where repeated reconstruction of the same events with the same binary reproduced different results. See [??? David's message] for details of the fix.

Paul [??? reported a different bug] and checked in a fix. This was giving different figure-of-merit values for repeated executions at the 1% level. See his message for details.
