synthpop.modules.extinction.nishiyama2009

Extinction law from Nishiyama et al (2009), for the direction of the Galactic center. We apply a a spline interpolation over the measurements provided in the paper.

Valid from 1.2 to 8.0 microns.

Extinction law from Nishiyama et al. 2009 Using a spline interpolation to estimate the extinction between 2.214 microns and 7.60 microns Use Alambda prop lambda^-2.0 for lambda l below 2 microns

extinction_law_name = 'Nishiyama2009'

law_ref_wavelength = 2.14

min_wavelength = 1.2

max_wavelength = 8.0

static determine_parameters()

creates an interpolation to the table data.

Alambda_Aref(eff_wavelength: float or np.ndarray) → float

Given an effective wavelength lambda_eff, calculate the extinction ratio A_lambda/A_ref

Parameters

eff_wavelengthfloat

wavelength to compute extinction ratio at [microns]
