GLAST LAT Project Dec Accomplishments • • • Flight Integration Support – Released bulk of code on Dec 12 • Tkr To. T 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 DC 2 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 all. Gamma 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 Tkr. Recon upgrade – First major tag released 1/4 – Plan to run 1 M all. Gammas to see how it looks Cal. Recon upgrade (Nov-Jan probably) – repeat from Dec report – Waiting for Tkr. Recon 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 Key Milestones q Start of Flight Integration – Jan 2005 q File transfer test with GSSC/ISOC – Jan 2005 - delayed q Mission GRT 1 – Feb 2005 – delayed a few months q DC 2 – July 2005 GSFC Monthly Review Jan 5 2005 - SAS 5

GLAST LAT Project Issues & Concerns q I&T support has been heavy load q Hardware will start arriving sometime… all our pieces have to be in place. q Thinking about DC 2 – must juggle I&T support with DC schedule q Getting the background rejection done in a timely fashion will be hard. May need to start it in parallel with Cal. Recon revamp GSFC Monthly Review Jan 5 2005 - SAS 6
