gammapy-meudon-tutorial

This repository aims to share instructions and material for the Tutorial taking place the 3rd October, 2017, in Meudon : https://indico.obspm.fr/event/22/

I Objectives

The goal of this day is to make an introduction to data analysis by playing with real scripts explained by experts. 3 sessions are organised:

• a Fermi tutorial: COSMAX
• an introduction to python
• a CTA tutorial with the package ctools
• a CTA tutorial with the package Gammapy

All files can be downloaded on your computer by typing on a terminal :

git clone https://github.com/bkhelifi/gammapy-meudon-tutorial.git

A backup site is set up to download data used for the CTA tutorials: https://www.dropbox.com/s/o4f5jczp42jjaw1/handson.zip?dl=0

For information, the open Data Format for gamma-ray astronomy is explained and described here: http://gamma-astro-data-formats.readthedocs.io/en/latest/index.html . This is a work in progress...

II Introduction tutorial: python and numpy

This tutorial is driven by Régis Terrier (APC).

It uses the notebook : notebooks/astropy_introduction.ipynb and notebooks/using_numpy.ipynb

PS: to start a notebook, type on a terminal : jupyter notebook toto.ipynb

III COSMAX : a Fermi tutorial

This tutorial is driven by Benoît Lott (CENBG).

IV ctools : a CTA tutorial

This tutorial is driven by Jürgen Knödlseder (IRAP).

V Gammapy : a CTA tutorial

This tutorial is spitted in different part.
