Science Data ProcessingScience Data Processing

– Receive Level 0 data from IOC

– Automatically process Level 0 data to Level 1

– Facilitate LAT monitoring and updates of calibrations

– Feed back high level monitoring info to IOC

– Generate Monte Carlo for instrument simulation, algorithm development etc

– Allow for data reprocessing

– Generate high level data products

– Develop analysis tools and platforms

– Deliver data products and algorithms to SSC

– Protect via archive all data, at SLAC and HEASARC

~ 3GB of data arrives per day~ 3GB of data arrives per day



The Critical AreasThe Critical Areas

• Simulation/reconstruction software

– Instrument simulation and reconstruction

– PSF, Aeff, background rejection

Supports instrument design and science studies

• Infrastructure

StatusStatus

• IOC is in formulation phase through FY’01

• Improving Simulation and Reconstruction

• Addressed infrastructure issues in 2000/2001 – support for the long run

• Providing balloon flight and PDR preparation support through summer ’01

• Continuing with requirements and specifications for science tools and calibrations, with first prototypes this year



SAS IssuesSAS Issues

• Heavy load on team to support both the balloon flight and PDR prep– Need additional 2-3 FTE for core and DPF work– Toby Burnett has pending NSF request

• Extremely important to our effort that it succeed!!– European & Japanese collaborators have committed to supporting

the core effort

• Want major Sim/Recon release by late 2001 to let us shift focus to Calibrations and analysis issues

• Need to get started on Data Processing Facility– Balloon & PDR support as early prototyping opportunities– Mock Data Challenge in mid 2002

• Technology for event, photon & exposure databases and techniques for indexing the photons (time, spatial tessellations)– Studies underway to evaluate technologies
