SkyPointSource

class gammapy.image.models.SkyPointSource(lon_0, lat_0, frame='galactic')

Bases: gammapy.image.models.SkySpatialModel

Point Source.

\[\phi(lon, lat) = \delta{(lon - lon_0, lat - lat_0)}\]

Parameters:

lon_0 : Longitude

\(lon_0\)

lat_0 : Latitude

\(lat_0\)

frame : {“galactic”, “icrs”}

Coordinate frame of lon_0 and lat_0.
