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.
