Corner plot of the parameters obtained from the fitted models to the simulated CTA spectrum. Maroon-colored contours and distributions are based on simulations with the SSC+π⁰ model fitted with the dual-component (ECPL+LP) model. The gray samples correspond to simulations based on the featureless ECPL model (i.e., no “bump”) that are also fitted with the dual-component model. Contour lines indicate the 11.8%, 39.3%, 67.5%, and 86.4% levels. The parameter E_peak denotes the peak energy of the LP component (in TeV). This is not a free model parameter, but was obtained from α and β – see Eq. (8).
