From the Figures and, it seems that a q-BWF component function is producing a peak and a related satellite small peak (we can easily see this fact observing the magenta lines). Alternatively, we could use the split-q-Gaussian functions, which are asymmetric too, but we need to add further components, to generate the satellite peaks. Using split-q-Gaussians for fitting, Figure turns into Figure . Here we can repeat the observation made by in the review about graphene and graphene oxide: to compare different fitting parameters of a Raman spectrum, it is fundamental the knowledge of the used fitting procedures. Once we have decided the number of components and their line shapes, we can compare parameters obtained from a set of Raman measurements. Moreover, there is no a priori reason to choose a particular function to fit the spectrum. Let us stress once more that Ferrari and Robertson suggested the BWF line shape for the G band in carbonaceous materials.
