Please consider that in literature about Fano resonance the parameter ξ is often given as 1/q (and with an opposite sign). Here the q-parameter is related to the Tsallis statistics. The q-BWF functions have been applied to the study of the Raman spectra of molybdenite, that is, the molybdenum disulfide, MoS2, using the Raman spectra from RRUFF database. Then, we applied q-BWFs to RRUFF spectra of rare-earth oxide REO glasses.
