redback.transient_models.extinction_models.extinction_afterglow_galactic_dust_to_gas_ratio(time, lognh, factor=2.21, **kwargs)[source]

Extinction with afterglow models using galactic dust-to-gas ratio

Parameters:

time – time in observer frame in days
lognh – log10 hydrogen column density
factor – factor to convert nh to av i.e., av = nh/factor (default 2.21)
kwargs – Must be all the parameters required by the base_model specified using kwargs[‘base_model’] plus: - redshift: source redshift (required) - av_mw: MW V-band extinction in magnitudes (default 0.0) - rv_host: host R_V parameter (default 3.1) - rv_mw: MW R_V parameter (default 3.1) - host_law: host extinction law (default ‘fitzpatrick99’) - mw_law: MW extinction law (default ‘fitzpatrick99’) Available extinction laws: ‘fitzpatrick99’, ‘fm07’, ‘calzetti00’, ‘odonnell94’, ‘ccm89’

Returns:

set by kwargs[‘output_format’] - ‘flux_density’, ‘magnitude’, ‘flux’, ‘spectra’ with extinction applied
