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:

1. nightly builds of GlueX software
2. b1pi reconstruction tests
3. 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.
