| P1 | 3.0 ± 0.3 | 1.12 ± 0.04 | 1.2 ± 0.1 | 0.81 ± 0.04 |
| P2 | 4.3 ± 0.4 | 0.78 ± 0.03 | 1.1 ± 0.1 | 0.70 ± 0.03 |

Notes. The normalization factor, N0, is given in units of 10-10 MeV-1 s-1 cm-2. The quoted errors are statistical at a 1σ confidence level. The systematic errors reported by the Fermi-LAT are of 14% on α and 4% on Ec (Abdo et al. 2013).
