Methods Documentation

evaluate(x, Av, bump_ampl)[source]¶

uv_bump(mu, bump_ampl)[source]¶

Drude profile for computing the UV bump.

Parameters:

x: np array (float): expects wavelengths in [micron]
x0: float: Central wavelength of the UV bump (in microns).
gamma: float: Width (FWHM) of the UV bump (in microns).
ampl: float: Amplitude of the UV bump.

Returns:

np array (float): lorentzian-like Drude profile

Raises:

ValueError: Input x values outside of defined range
