GLAST LAT Project Gamma-ray Large Area Space Telescope GLAST Large Area Telescope WBS 4.1.D SAS GSFC Monthly Review Period Ending: Jan 2005 Richard Dubois LAT SAS Subsystem Manager GSFC Monthly Review Jan 5 2005 - SAS 1 GLAST LAT Project Dec Accomplishments • • • • • Flight Integration Support – Released bulk of code on Dec 12 • Tkr ToT calibrations by end January • Updated CAL calibrations delivered after Xmas – Pipeline handled Xmas-break data fine • Still an issue with error handling of scripting errors in user scripts User Workbook going great guns – More polishing on the New User introduction – Documenting use of FRED event display now Java data handling tools proposal – We have adopted this approach – Tony Johnson (SLAC) has agreed to manage our data handling projects – First new system tests interface to hit the street Jan 15. Things are happening. – J-P Lefevre from Saclay to arrive for 6-month sabbatical around 1/24 • Has java experience for data servers on 2 astro missions Software developer in charge of Release Manager left group – Replacement req just hit the street DC2 Coordinating Committee – Starting to define sky model – Aiming for end Feb for a testable model GSFC Monthly Review Jan 5 2005 - SAS 2 GLAST LAT Project Upcoming for January • • • • • I&T deliverables – Keep working on TKR Tot – Keep working on more sophisticated CAL calibrations based on what’s been learned during assembly at NRL Gino pipeline functioning – Keep testing it – Ran 2 allGamma MC runs over Xmas (twice, in fact) • Completely smooth. Now have tools for metering MC jobs into the pipeline and for accessing the data catalogue from compiled code TkrRecon upgrade – First major tag released 1/4 – Plan to run 1M allGammas to see how it looks CalRecon upgrade (Nov-Jan probably) – repeat from Dec report – Waiting for TkrRecon to finish up – David Chamont (LLR/Paris) visiting next week to discuss the changes – Add clustering and “MIP-segment” finding Send out req for Infrastructure position GSFC Monthly Review Jan 5 2005 - SAS 3 GLAST LAT Project Timeline Tkr Tower B?

Thinking about DC2 – must juggle I&T support with DC schedule Getting the background rejection done in a timely fashion will be hard. May need to start it in parallel with CalRecon revamp GSFC Monthly Review Jan 5 2005 - SAS 6
