Phenomenological models used to fit the source spectral continuum.
| Model | Photon energy distribution |
|---|---|
| CUTOFFPL | N(E) = KE−αexp(−E/β) |
| PO × HIGHECUT | M(E) = KE−αexp[(Ec − E)/Ef], (E ≥ Ec) |
| M(E) = KE−α, (E ≤ Ec) | |
| NPEX | N(E) = (A1E−α1 + A2E+α2)exp(−E/kT) |
| FDCUT | N(E) = APLE−Γ/[exp((E − Ecut)/Efold)+1] |
| COMPTT | Comptonization model from Titarchuk (1994) |
