DiskSource

class marxs.source.DiskSource(**kwargs)

Bases: RadialDistributionSource

Astrophysical source with the shape of a circle or ring.

This source uses a small angle approximation which is valid for radii less than a few degrees and runs much faster. See SphericalDiskSource for an implementation using full spherical geometry.

Parameters:

a_inner, a_outerastropy.coordinates.Angle

Inner and outer angle of the ring (e.g. in arcsec). The default is a disk with no inner hole (a_inner is set to zero.)

Define a new MARXS element.
