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.

Fermitools Documentation

Welcome to the Fermitools! The Fermitools consists of the basic tools necessary to analyze Fermi data. And this is the place to begin to learn how to install and use these tools.

The documentation consists of four sections that will be useful to you at different stages of your mastery of the Fermitools:

  • Installing the Fermitools — instructions for installing the Fermitools
  • LAT Analysis Start Page — A single source for all the information you should need to get started analyzing LAT data.
  • Analysis Threads — step by step description of a standard Fermitools analysis
  • Cicerone — a detailed description of the analysis environment and its methodology. The Cicerone describes the full Fermitools.
  • Reference Manual — a description of each tool and its input.

So how should you begin? This depends on your learning style. If you have a basic understanding of analyzing gamma-ray spectra, know something about the LAT and/or the GBM, and like to learn by example, then you might want to start by installing the Fermitools, and then work through the analysis threads.

On the other hand, if you are new to gamma-ray burst spectroscopy, or you would like a more systematic approach, then you might want to start by reading the Cicerone.

To learn about all of a tool's parameters or to remember how to use a tool with which you are already familiar, see the Reference manual.

The documentation is written to be comprehensive and self-contained, and we will update it based on the comments from the user community. If you have some questions, you should first check the FSSC Frequently-Asked-Questions; your question may already have been answered. Finally, you can request assistance through the FSSC helpdesk.
