- None
Notes
From Chiar & Tielens (2006, ApJ, 637 774)
Example showing the average curve
import numpy as np import matplotlib.pyplot as plt import astropy.units as u from dust_extinction.averages import CT06_MWLoc fig, ax = plt.subplots() # define the extinction model ext_model = CT06_MWLoc() # generate the curves and plot them x = np.arange(1.0/ext_model.x_range[1], 1.0/ext_model.x_range[0], 0.1) * u.micron ax.plot(x,ext_model(x),label='CT06_MWLoc') ax.plot(1.0/ext_model.obsdata_x, ext_model.obsdata_axav, 'ko', label='obsdata') ax.set_xlabel(r'$\lambda$ [$\mu m$]') ax.set_ylabel(r'$A(x)/A(V)$') ax.legend(loc='best') plt.show()

Methods Documentation
- evaluate(x)[source]¶
CG06 MWLoc function
- Parameters:
- x: float
expects either x in units of wavelengths or frequency or assumes wavelengths in wavenumbers [1/micron]
internally wavenumbers are used
- Returns:
- axav: np array (float)
A(x)/A(V) extinction curve [mag]
- Raises:
- ValueError
Input x values outside of defined range
