trident.spectrum_generator.SpectrumGenerator.add_milky_way_foreground

SpectrumGenerator.add_milky_way_foreground(flux_field=None, filename=None)[source]

Postprocess a spectrum to add a Milky Way foreground. Data from Charles Danforth. Median-filter of 92 normalized COS/G130M+G160M AGN spectra spanning the wavelength range of 1130 to 1800 Angstroms in 0.07 Angstrom bin size.

Parameters

Flux_field

optional, array

Array of flux values to which the Milky Way foreground is applied. Default: None

Filename

string

Filename where the Milky Way foreground values used to modify the flux are stored. Default: None

Example

Make a one zone ray and generate a COS spectrum for it. Add MW foreground to it, and save it.

>>> import trident
>>> ray = trident.make_onezone_ray()
>>> sg = trident.SpectrumGenerator('COS')
>>> sg.make_spectrum(ray)
>>> sg.add_milky_way_foreground()
>>> sg.plot_spectrum('spec_mw_corrected.png')

Plot a naked MW spectrum.

>>> import trident
>>> sg = trident.SpectrumGenerator('COS')
>>> sg.add_milky_way_foreground()
>>> sg.plot_spectrum('spec_mw.png')
