Parameters of the joint spectral fit to the gamma-ray SED obtained with MAGIC and Fermi-LAT data.
| Fit | LP | EPWL |
|---|---|---|
| f0 | 34.2 ± 1.1 | 41.7 ± 2.2 |
| Γ | −2.76 ± 0.03 | −2.05 ± 0.03 |
| E0 | 180.77 | 198.21 |
| β | 0.26 ± 0.02 | – |
| Ec | – | 492 ± 35 |
| χ2/d.o.f. | 66.97/11 | 19.18/11 |
Notes. A power law with exponential cutoff (EPWL) following dN/dE = f0 (E/E0)−Γ exp(−E/Ec) and a log parabola (LP) dN/dE = f0(E/E0)−Γ − βlog(E/E0) are tested. The flux normalizations f0 are given in units of 10−10 Te V−1 cm−2 s−1, and energies in GeV. Only statistical errors are given. The pivotal energy E0 is evaluated to minimize the correlation between f0 and Γ.
