The Standard Analysis Environment

• The Standard Analysis Environment (SAE) are the tools andcalibration data needed for routine analysis of LAT data.

• The SAE will be used by the LAT team and the generalscientific community.

• This environment was defined jointly by the LAT team andthe GSSC.– The development is managed by the LAT team.– The GSSC is providing manpower and expertise with the

HEASARC coding standards.

Analysis software

• LAT Managed– Data Challenge Release 1 (12/15/03)—basic capabilities such

as accessing the principal databases, fitting source modelswith the likelihood tool, binning burst counts into spectra,creating burst response matrices and fitting burst spectra.

– Data Challenge Release 2 (1/15/06)— completion of basiccapabilities, especially the addition of graphics to the tools.Basic pulsar tools.

– Data Challenge Release 3 (8/06)— completion of tools.Integration of analysis of GBM data.

• All science tools to be delivered to the GSSC for packagingand initial distribution to the Community– Post-DC3 (1st quarter 2007)

• GSSC Managed– Packaging of the tools for distribution to the community
