The HEASARC welcomes your participation in a brief survey to capture how users access and utilize HEASARC data, software, and services. The outcome(s) of this survey will be used to guide, prioritize, and plan our activities and development in the coming years. It contains 18 questions, generally takes just a few minutes to complete, and your answers will remain totally anonymous. We thank you in advance for your valuable feedback.

LAT Data Products

The following lists the science data products created by the LISOC (the LAT Instrument and Science Operation Center) and provided to the FSSC.

LAT Photon and Extended Data

High-level Data Products

Daily Data Products

The following data products are created daily by the LISOC and sent to the FSSC. The products are create after each downlink from the spacecraft (6-8 per day).

ID Name Description
LS-001 LAT Events Large number of parameters describing a large subset of the events telemetered to the ground (many did not result from photons).
LS-002 LAT photons Selected parameters from the subset of events identified as gamma-ray photons
LS-005 LAT Pointing and Livetime History LAT orientation and mode at 30-second intervals; used to calculate exposures
LS-020 LAT Pointing and Livetime History LAT orientation and mode at 1-second intervals; used to calculate exposures

Periodic Data Products

The following data products will be created periodically.

ID Name Description
LS-008 LAT Point Source Catalog Table of detected gamma-ray sources with derived information
LS-010 Interstellar Emission Model Model for diffuse gamma-ray emission from the Milky Way, input for high-level data analysis; will be refined using Fermi data. The Interstellar Emission Model is incorporated into the the Fermi Science Tools. However, investigators may occasionally need to obtain updates of this model from the FSSC web site.
