The image is giving a screenshot of Fityk, where we used a script to define the q-BWF functions. The data (green dots) are those of the Raman spectrum of a MoS2 pyramid available in Zenodo, . The q-BWF components are in red, and the sum of the components in yellow. The parameters of the two main q-BWFs of pyramid are given in the figure. Note the values of q being 1.71 and 1.92 for the two q-BWF functions related to MoS2.
