Characterization of the HGPS spectral data for the 25 selected γ-ray sources.
| Quantity | Minimum | Maximum | Median |
|---|---|---|---|
| Emin (TeV) | 0.3 | 1.47 | 0.4 |
| Emax (TeV) | 6.32 | 31.62 | 12.71 |
| ξ | 1.6 | 2.5 | 2.4 |
| Livetime (h) | 4.0 | 259.0 | 17.0 |
| Γ | 1.81 | 2.69 | 2.31 |
| ϕ0 (TeV−1 cm−2 s−1) | 1.80e−13 | 1.56e−11 | 3.51e−12 |
| η (%) | 0.0 | 8.8 | 1.7 |
| S | 1.5 | 22.8 | 4.3 |
Notes. The columns show the minimum, maximum, and median of the distribution of the quantity in the corresponding row for the selected sources. Emin and Emax are the minimal and maximal bin-center energy of selected spectral points. The livetime is the dead-time-corrected observation time as obtained from the HGPS dataset. Γ and ϕ0 are the best-fit index and flux normalization for a power-law model. The binning factor ξ, error asymmetry η, and spectral point significance S are defined in Sect. 3.2.
