redback.transient_models.spectral_models.band_function_high_energy(energies_keV, log10_norm, alpha, beta, e_peak, redshift=0.0, **kwargs)[source]

Band function (Band et al. 1993) spectrum.

Parameters:

energies_keV – energy array in keV (observer frame)
log10_norm – log10 photon flux normalization at 100 keV (photons/cm^2/s/keV)
alpha – low-energy photon index
beta – high-energy photon index
e_peak – peak energy in keV
redshift – optional redshift. If provided (>0), parameters are treated as rest-frame and energies are shifted accordingly. If set to 0, parameters are treated as observer-frame (typical when z is unknown).

Returns:

flux density in mJy
