Results from the spectral fits performed to the MAGIC data alone (first row) to a power law function (PL), and from the joint fits to Fermi-LAT and MAGIC data (abbreviated as F & M) to power laws with exponential (PL Exp) or sub-exponential (PL Subexp) cut-offs, and to a log-parabola model (LP).

Notes. For the last two fits only Fermi-LAT spectral points above 10 GeV were used. The normalisation factor F0 is given in units of TeV−1 cm−2 s−1. The normalisation energy, E0, and the cut-off energy, Ec, are given in units of GeV. Also, Γ refers to the PL spectral index, and β to the cut-off strength, except for the LP case for which β represents the curvature of LP. The quoted uncertainties are statistical at a 1σ confidence level.
