SkyDiffuseCube

class gammapy.cube.models.SkyDiffuseCube(map, norm=1, meta=None, interp_kwargs=None, name='diffuse')

Bases: gammapy.cube.models.SkyModelBase

Cube sky map template model (3D).

This is for a 3D map with an energy axis. Use SkyDiffuseMap for 2D maps.

Parameters:

map : Map

Map template

norm : float

Norm parameter (multiplied with map values)

meta : dict, optional

Meta information, meta[‘filename’] will be used for serialization

interp_kwargs : dict

Interpolation keyword arguments passed to gammapy.maps.Map.interp_by_coord. Default arguments are {‘interp’: ‘linear’, ‘fill_value’: 0}.
