| Power-law | −11.48 ± 0.03stat ± 0.02sys | −2.25 ± 0.02stat ± 0.03sys | – | 26.6/13 | |
| Log-parabola | −11.43 ± 0.04stat ± 0.03sys | 2.37 ± 0.04stat ± 0.03sys | −0.08 ± 0.02stat ± 0.01sys | 7.9/12 | |
Notes. The functions are of the form f(x) = log 10(dN/ dE) = p0 + p1x and f(x) = log 10(dN/ dE) = p0 + p1x + p2x2 with x ≡ log 10(E/ 100 GeV).
