In our decomposition, the distance of components' centres, at 515.5 and 524.5 cm -1 respectively, is of about 9 cm -1 . Of course, the sample is different. Besides the depolarized data, the web page is also providing data with three different directions of polarization of laser relative to fiducial mark: 0 ccw, 45 ccw and 90 ccw (see please the plot at this link). If we use R060277 polarized 0 ccw Raman spectrum processed data, we have two q-Gaussian components having q=1.38, centre at 516 cm -1 , and q=1.68 at 525.5 cm -1 (see Appendix B). For R060277 polarized 45 ccw Raman spectrum data processed, we have q=1,34, 516.5 cm -1 , q=1.74, 526.5 cm -1 . In the case R060277 polarized 90 ccw Raman spectrum data processed, we find q=1.38, 517.5 cm -1 , q=1.67, 526 cm -1 . The plots are like that given in the Fig. . Let us stress that these are unconstrained fits, obtained just guessing the existence of two components, without any further information.
