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

A diffuse source.

This can be used for example to simulate the interstellar radiation field. This source emits inwards.


name : str, optional

The name of the source

peeloff : bool, optional

Whether to peel-off photons from this source


Any additional arguments are are used to initialize 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).
map The relative luminosity in each cell, given as a Numpy array or an AMRGridView instance
