Interstellar are objects representing model
interstellar processes which modify source intensities.
Base class for model interstellar X-ray processes (e.g., attenuation).
Attenuate a (specific) photon flux signal in-place.
- energies (ndarray[m[,n]]) – An array of energies in keV at which attenuation factors need to be applied to the corresponding elements of the signal array.
- energies – A signal array to be attenuated, where the second dimension (columns) is optional and generally represents time (phase). The number of rows must be equal to the number of energies.
It is expected that the operations performed on a column of specific fluxes need to be applied identically to all other columns. The referenced object
signalneeds to be directly modified in-place, and not copied.
Return the attenuation factor at a set of energies.
The attenuation model can depend on fixed or free variables in the subspace, and generally requires loading model data from disk.
Parameters: energies (ndarray[m]) – An array of energies in keV at which attenuation factors are requested. Returns: An array of attenuation factors, one at each input energy.
