Making REST skims
Paul reviewed the change that he checked in to allow users to skims of REST format data. Previously the REST-writing capability was bound up with other code used during the data challenge. See his email for details.
Simple Email Lists: Mark
Mark reviewed the mechanism we are using for three notification-type email lists:
- nightly builds of GlueX software
- b1pi reconstruction tests
- single-track reconstruction tests
The system is described on [Simple Email Lists|his wiki page]. The idea is to have a light-weight system suited for cron jobs and targeted at a limited audience.
No more hardwired run numbers
David reviewed his announcement of changes that removed a few instances of hard-wired run numbers in our code. Up until recently there was no run dependence in calibration constant look-up, so there was little practical effect.
Switch back to use of public version of ROOT at JLab?
Mark proposed that at JLab, we go back to using the IT-Division-provided versions of ROOT. Some months ago we switched to using privately built (Hall D specific) versions. The intent is to support any effort IT Division makes to support physics analysis in general by using the products they offer, i. e. demonstrate that we can play nice with others. There was general support for this move. Mark will work on making the change.
HDDM changes: Richard
We reviewed some proposed changes from Richard to rationalize the data model for Monte Carlo data to more clearly identify information that is known only from the simulation and would not be available in real data. This information had been incorporated in a somewhat ad hoc fashion. The need for this information is real; this is an attempt to clean up the implementation. See his talk, presented in various versions at a series of meetings held over the past couple of weeks, for details of the proposal. Feedback from David, Beni, Simon, and Mark has been incorporated in the plan.
Richard wants to do these changes before doing a conversion of the simulation from Geant3 to 4. He hopes to have this set of changes done by the Summer.
