MapDatasetMaker

class gammapy.makers.MapDatasetMaker(selection=None, background_oversampling=None, background_interp_missing_data=True)[source]

Bases: gammapy.makers.Maker

Make maps for a single IACT observation.

Parameters
selectionlist

List of str, selecting which maps to make. Available: ‘counts’, ‘exposure’, ‘background’, ‘psf’, ‘edisp’ By default, all maps are made.

background_oversamplingint

Background evaluation oversampling factor in energy.

background_interp_missing_data: bool

Interpolate missing values in background 3d map. Default is True, have to be set to True for CTA IRF.
