Btw., if that is interestting, I have also written a 
scipy-only-dependency implementation of Tepper-Garcia (2006) Voigt 
profile approximation, if that could be of interest for e.g. the 
modeling module or maybe a spectools module.

The upside to it is it is  precise and is expressed in terms of physical 
units - column density and broadening parameter - and hence can be fed 
directly to software like e.g. VPfit, and it is easdily interpreted. The 
downside to this is ithat it needs information about the line's 
resonator strength and rest wavelength, the former found by aid of the 
latter. For ths I am so far for my personal use depending on the list 
from VPfit, but any list of similar format would of course do.
