voigt

ChiantiPy.tools.filters.voigt(wvl, wvl0, factor=(0.5, 1.0))[source] [edit on github]

pseudo-Voigt filter the sum of a Gaussian and a Lorentzian

Parameters:

wvl : ndarray

Wavelength array

wvl0 : float64

Wavelength the filter is centered on.

factor: array-type

contains the following 2 parameters

A : float64

relative size of gaussian and lorentz components must be between 0. and 1. but this is not currently checked

sigma: `~numpy.float64`

the gaussian width of the gaussian profile (the standard deviation) also creates the lorentz component with the same fwhm
