Gammapy hands-on workshop for University of Adelaide and CTA-Oz

Hands-on workshop on VHE data analysis using Gammapy

This folder contains the analysis notebooks shown in the Gammapy hands on sessions for University of Adelaide and CTA-Oz. The related indico page can be found at https://indico.cta-observatory.org/event/5395/

Installation and set-up

These instructions assume that you have previously installed a version of Anaconda or Miniconda on your machine.

Gammapy installation

We recommend that you install the latest version of gammapy as follows:

curl -O https://gammapy.org/download/install/gammapy-1.2-environment.yml
conda env create -f gammapy-1.2-environment.yml
conda activate gammapy-1.2

OR with pip

python -m pip install gammapy[all]

Download tutorials & associated data

To download the tutorials and associated datasets (necessary for the tutorials in this workshop)

gammapy download notebooks
gammapy download datasets

If using conda environment, set GAMMAPY_DATA with conda

conda env config vars set GAMMAPY_DATA=$PWD/gammapy-datasets/1.2
conda activate gammapy-1.2

else set with shell:

export GAMMAPY_DATA=$PWD/gammapy-datasets/1.2

Check your installation

To check that the gammapy environment is working, open a new terminal and type

conda activate gammapy-1.2
gammapy info

To further check that you have correctly set up the data folder type

ipython

Then in the ipython window, type

from gammapy.data import DataStore
ds = DataStore.from_dir("$GAMMAPY_DATA/hess-dl3-dr1")
obs = ds.get_observations()
print(len(obs))

If the cells run without any error and prints 105, Congratulations! You have correctly set-up gammapy

If you have any issues with installation please contact Kirsty via email [email protected]
