Detected spectral energy distribution of M 87 data with H.E.S.S. The best-fit LPxEBL finke2022 spectral models are shown in yellow for the reduced energy range (0.3 − 10 TeV) and in purple for the full energy range (0.3 − 32 TeV). The best-fit PL spectrum for the low-state data (based on H.E.S.S. Collaboration 2023) is shown for comparison in blue. The color bands show the 1σ uncertainty contours. The upper limit (UL) in the last bin of the low-state spectrum is defined at a 95% confidence level (c.l.).
