Workshop on the development of tools for reconstructing beamtest data from the Gamma-ray Large Area Space Telescope (GLAST). The workshop, held on March 21, 2006, discussed existing tools and future developments, focusing on processing of simulated events, data input, and ntuple generation.

What Exists Now • Standard Gleam knows about the CU • toy geometry • multiple incident particles • Checkout package about to appear • will guarantee a consistent test of packages • place to collect macros, etc.
What doesn’t exist yet • ACD analysis • Processing of ancillary data • Will Gleam do this? • Output of truncation info • TBD
GLEAM as Event Monitor Do minimal processing: • Data input • Files • Simultaneous sampling from multi-caster? • Conversion to digis • Clustering in Trackers and Calorimeters • Truncation Analysis • TBD
Gleam as an quick ntuple generator • Run on EBF files to process entire runs • Digitize • Minimal Recon: cluster, truncation, TBD • TBD ntuple generation (no track info) • Rates (just clustering so far): • 3-GeV photons, “full” trigger – 500 evt/sec • 250-GeV electrons – 50 evt/sec • 1 15-second period ~ 2 cpu seconds
