Installation and setup

Required softwares

• Install the Fermitools (https://github.com/fermi-lat/Fermitools-conda)
• Install PolSpice
• Install healpy python package

Setting up the environment

Set the environment in your .bashrc or .bash_profile:

function Xgam_env {
	echo 'Setting Xgam environment...'
	conda activate fermi
	export PYTHONPATH=:/path/to/this/package/:${PYTHONPATH}
 	export PATH=/path/to/this/package/Xgam/bin:${PATH}
	export P8_DATA=/path/to/data_files
	echo 'done.'}

Change the directory where the data files are stored in init.py (line 35):

FT_DATA_FOLDER = '/path/to/data_files'

In the data directory should there be the following folders:

• photon/ -> where FT1 files are stored
• spacecraft/ -> where FT2 files are stored
• output/ -> where ST outputs will be stored
