Top panel: photon–photon absorption correction (exp[τγγ]) for the source Centaurus A at 3.8 Mpc, based on the EBL model by FR2017. Bottom panel: observed (filled black squares) and model interpolated intrinsic spectrum (red line), and the absorption-corrected (black line) spectrum are reported. The two sensitivity limits for CTA are shown; see caption to Fig. 6.
