easyfermi 1.0.5

The easiest way to analyze Fermi-LAT data

easyFermi

The easiest way to analyze Fermi-LAT data.

Requirements

easyFermi relies on Python 3, Fermitools and Fermipy.

We recommend the user to install Miniconda 3 or Anaconda 3 before proceeding.

To install Fermitools with conda, do:

$ conda create -n fermi -c conda-forge -c fermi fermitools python=3 clhep=2.4.4.1

If you have problems with the installation of Fermitools, please take a look on the video tutorial here: https://fermi.gsfc.nasa.gov/ssc/data/analysis/video_tutorials/

Now that you installed the Fermitools, you can install Fermipy with the following command:

$ conda install --name fermi -c conda-forge fermipy matplotlib=3.3.2

Note that Fermipy doesn't work properly with more recent releases of matplotlib. This is why we are installing matplotlib V3.3.2 here.

For more details, check the documentation of Fermipy here: https://fermipy.readthedocs.io/en/latest/install.html

Installing easyFermi

Now you just have to open the fermi environment with

$ conda activate fermi

And then install easyFermi with pip:

$ pip install easyFermi

Usage

While in the fermi environment, do:

$ python
>>> import easyFermi

Fermipy light curve problem

In Fermipy V1.0.1 (Python 3), some users face a "KeyError: 'fit_success'" issue when trying to build the light curves.

This issue is solved here: https://github.com/fermiPy/fermipy/issues/368
