SpectrumDatasetMaker

class gammapy.makers.SpectrumDatasetMaker(selection=None, containment_correction=False)[source]

Bases: gammapy.makers.Maker

Make spectrum for a single IACT observation.

The irfs and background are computed at a single fixed offset, which is recommend only for point-sources.

Parameters
selectionlist

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

containment_correctionbool

Apply containment correction for point sources and circular on regions.
