Fermi-LAT

The Fermi Large Area Telescope (LAT) observes the gamma-ray sky from 20 MeV up to 1 TeV. It does so by scanning the entire sky three times a day, hence, there is gamma-ray data available for each day for every position on the sky.

The following

Installation & preparation

To analyse data from Fermi-LAT, the Fermitools are needed. Additionally, there is a python package, called fermipy, such that one can do the data analysis from within a python environment. There are analysis scripts, written using fermipy, available to create either a spectrum or a light curve, which are available at $FERMITOOLS, linking to /software/Science/satscripts/fermiscripts.
To run those scripts, it is necessary to have both the Fermitools and fermipy installed, ideally in a conda environment. There are two options for the user to do so: creating the corresponding conda environment yourself, or calling a currently existing conda environment.

Option 1 - Installing and creating a conda environment yourself

Both the Fermitools and fermipy are managed via GitHub and the full code, documentation and installation can be found at
