:orphan: .. include:: ../references.txt .. _tutorials: ========= Tutorials ========= **Notice :** it is advised to first read :ref:`package_structure` of the User Guide before using the tutorials. This page lists the Gammapy tutorials that are available as `Jupyter`_ notebooks. You can read them here, or execute them using a temporary cloud server in Binder. To execute them locally, you have to first install Gammapy locally (see :ref:`installation`) and download the tutorial notebooks and example datasets (see :ref:`getting-started`). Once Gammapy is installed, remember that you can always use ``gammapy info`` to check your setup. Gammapy is a Python package built on `Numpy`_ and `Astropy`_, so to use it effectively, you have to learn the basics. Many good free resources are available, e.g. `A Whirlwind tour of Python`_, the `Python data science handbook`_ and the `Astropy Hands-On Tutorial`_. .. raw:: html

Introduction ============ The following three tutorials show different ways of how to use Gammapy to perform a complete data analysis, from data selection to data reduction and finally modeling and fitting. The first tutorial is an overview on how to perform a standard analysis workflow using the high level interface in a configuration-driven approach, whilst the second deals with the same use-case using the low level API and showing what is happening *under-the-hood*. The third tutorial shows a glimpse of how to handle different basic data structures like event lists, source catalogs, sky maps, spectral models and flux points tables. .. raw:: html

However, for long-running, non-interactive tasks like data reduction or survey maps, you might prefer a Python script.
