Announcements

1. CCDB is now required to build sim-recon.
2. There is a new release of HDDS, 1.5. This fixes some geometry issues and is needed to go along with the corresponding changes in the tracking code.
3. The new release of sim-recon, sim-recon-2013-01-11, uses CCDB 0.06 and HDDS 1.5. Note that as of this writing, the recent bug fix from David for the REST format is not part of the release.

There was some discussion about the meaning of the date in the sim-recon releases. Note that the date corresponds to the date when the tag was first made from the trunk and not the date that the release is announced. In general, not all of the code in a release will correspond to the date in the tag name. Changes may have to be introduced to fix bugs.

Data Challenge Status

Not a lot has moved on analysis of data challenge data lately. Justin Stevens of MIT has been looking at them however. He expressed an interest in generating skims, to reduce processing time for selected channels. Paul is working on reconfiguring code in the REST plugin to facilitate skim creation.
