hyperion.sources.ExternalSphericalSource

class hyperion.sources.ExternalSphericalSource(name=None, peeloff=True, **kwargs)

An spherical external source.

This can be used for example to simulate the interstellar radiation field. This source is similar to SphericalSource but emits photons inwards.

Parameters:

namestr, optional

The name of the source

peeloffbool, optional

Whether to peel-off photons from this source

Notes

Any additional arguments are are used to initialize attributes.

Attributes

name	A string identifying the source (optional)
luminosity	The bolometric luminosity of the source (ergs/s)
temperature	The temperature of the source (K)
spectrum	The spectrum of the source, specified either as an astropy.table.Table instance with 'nu' and 'fnu' columns, or as a (nu, fnu) tuple, where the frequency is given in Hz, and the flux is given as F_nu (units are unimportant since the normalization is set by the luminosity).
position	The cartesian position of the source (x, y, z) as a sequence of three floating-point values (cm)
radius	The radius of the source (cm)
