containment_region#
- gammapy.maps.containment_region(map_, fraction=0.393, apply_union=True)[source]#
- Find the iso-contours region corresponding to a given containment
for a map of integral quantities with a flat geometry.
- Parameters:
- map_
WcsNDMap Map of integral quantities.
- fractionfloat, optional
Containment fraction. Default is 0.393.
- apply_unionbool, optional
It True return a compound region otherwise return a list of polygon regions. Default is True. Note that compound regions cannot be written in ds9 format but can always be saved with numpy.savez.
- map_
- Returns:
- regionslist of
PolygonSkyRegionorCompoundSkyRegion Regions from iso-contours matching containment fraction.
- regionslist of
