GLAST LAT Project
Science Tools Workshop, June 12-14, 2002
Analysis Tools Breakout Session
•
Identified four groups of tools
– Pulsars—lift existing tools. Applicable to binaries?
– GRBs—applicable to both GBM & LAT. Treat LAT data in limit
where burst is signal above definable background
– Catalog comparison—need to quantify confidence
– Likelihood tool—“Swiss knife” for fitting source parameters,
source detections, upper limits, etc.
•
Many tools need to be split into separate tools
– Verifying a pulsar ephemeris and searching for P, P-dot
– Barycentric corrections and phase assignments
– Binary and pulsar periods?
•
Testing
– Challenge tools with simulated data, EGRET data
– Formal data challenges
– Document testing

Analysis Tools, cont.
• Available human resources identified
• Requirements need more work for the September review. There
was little detailed discussion of specifics. The interfaces need
to be defined clearly.
• Requirements editors assigned
