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
