In the study of diamond Raman spectra, we noted that the far-wings of Kaniadakis Gaussians, pseudo-Voigt and Voigt functions seem being more "Lorentzian" that those of the Tsallis Gaussians. In the cases here proposed for anatase, and previously for graphite, we can see that the wings are properly described by q-Gaussians, and therefore no further functions have been considered for fitting.
