Datasets

class gammapy.datasets.Datasets(config=None)

Bases: object

Download and access for all built-in datasets.

TODO: this isn’t used much at the moment and not documented. I added this before I decided to add gammapy_extra, and then this class wasn’t needed to access datasets for tests.

We still need something like this to manage files that aren’t in gammapy-extra, e.g. large files from the web that we don’t want to stick in gammapy-extra.

This class has overlap with the gammapy.data.DataManager class … maybe it should be merged or maybe it’s better to keep that one focused on HESS (and Fermi?) data management?

Parameters:

config : OrderedDict

Data manager configuration.
