make_map_background_irf#
- gammapy.makers.utils.make_map_background_irf(pointing, ontime, bkg, geom, oversampling=None, use_region_center=True)[source]#
Compute background map from background IRFs.
- Parameters
- pointing
FixedPointingInfo
orSkyCoord
Observation pointing
If a
FixedPointingInfo
is passed, FOV coordinates are properly computed.If a
SkyCoord
is passed, FOV frame rotation is not taken into account.
- ontime
Quantity
Observation ontime. i.e. not corrected for deadtime see https://gamma-astro-data-formats.readthedocs.io/en/latest/irfs/full_enclosure/bkg/index.html#notes) # noqa: E501
- bkg
Background3D
Background rate model
- geom
WcsGeom
Reference geometry
- oversampling: int
Oversampling factor in energy, used for the background model evaluation.
- use_region_center: bool
If geom is a RegionGeom, whether to just consider the values at the region center or the instead the sum over the whole region
- pointing
- Returns
- background
WcsNDMap
Background predicted counts sky cube in reco energy
