Linear regression analysis of the observed spectrum of 1ES 0229+200 in the MeV–TeV energy band.

Photon energy MeV−GeV 1 TeV

Γ(σ) 1.93 ± 0.06 2.27 ± 0.13
r 0.99 0.98
N 13 13
p <0.0001 <0.0001

Notes. The linear regression is obtained by considering the photon energy Eγ to be the independent variable and assuming a relation dNγ(Eγ)/ d; N is the number of points, r is the correlation coefficient, and p is the chance probability.
