Table 4.
Best-fit parameters of an ECPL electron distribution in the form dN/dE = N0(E/E0)−αexp(−(E/Ec)), where E0 is the energy scale, α the spectral index, and Ec the cutoff energy.
| Parameter | Best fit value | Frozen |
|---|---|---|
| E0 [TeV] | 1 | True |
| Ee, min [GeV] | 0.1 | True |
| Ee, max [TeV] | 1000 | True |
| N0 [×1043 TeV−1] |
 |
False |
| Ec [TeV] |
 |
False |
| α | 1.5 ± 0.4 | False |
Notes. Normalization of the spectrum N0 is calculated for the source distance of 1 kpc. VHE-UHE emission of LHAASO J2108+5157 is assumed to be dominated by emission due to IC scattering of electrons on CMB (T = 2.83 K, u = 0.26 eVcm−3) and FIR (T = 20 K, u = 0.3 eVcm−3) seed photon fields.
