Announcements

  • report from June Software Review exists in draft form.
  • bash set-up for GlueX software ready for beta-testing
  • Elliott and Carl Timmer have complete EVIO version 4 working
    • random access io
    • support for dictionaries
    • contact Elliott for more information

Review of Minutes from the Last Meeting

  • new BCAL digitization, in the repository,
    • bcal meeting minutes has instructions for use
    • available for early adopters

Sub-group reports

Tracking

  • Simon checked in routine for DReferenceTrajectory class to propagate error matrix
  • vertex code almost ready
  • Beni providing interesting events errors and bug

PID

  • Paul just checked in a bunch of changes, minor
    • moving pid info into dkinematic data
    • added time variable to DKinematicData
    • start counter, tof, time at vertex
    • added covariance matrix for neutral showers
  • kinematic fitting, functional, vertex fit work, time not tested, multi-vertex not yet
  • analysis software, largely finished, almost ready to check-in
  • difference between REST and using raw data, needs to be tracked down

CCDB Status

See Dmitry's slides.

  • Program for full implementation discussed with Mark
  • SQLite support added

Raw data tape

  • should be done soon
  • translation table, crate/slot/channel to jana object needed
  • read in evio event, for each bank, hardware translation
  • XML formatted table in current implementation
  • Dave and Elliott will figure it out
