We have used Gaussian shape of individual phonon replicas for fitting the experimental curve as suggested by Collan and Krustok. Better fit has been obtained using the parameters E0 (zero phonon energy)=1.28 eV, Eph (phonon energy)=0.038 eV, δ (phonon broadening parameter)=0.026 eV and S (Hwang–Rhys factor)=2.13. Thus, the results of Pal and Bose remain unchanged. Fitting parameters used by Collan and Krustok have no physical significance.
