ExponentialCutoffPowerLaw3FGL

class gammapy.spectrum.models.ExponentialCutoffPowerLaw3FGL(index, amplitude, reference, ecut)

Bases: gammapy.spectrum.models.SpectralModel

Spectral exponential cutoff power-law model used for 3FGL.

Note that the parmatrization is different from ExponentialCutoffPowerLaw:

\[\phi(E) = \phi_0 \cdot \left(\frac{E}{E_0}\right)^{-\Gamma} \exp \left( \frac{E_0 - E}{E_{C}} \right)\]

Parameters:

index : Quantity

\(\Gamma\)

amplitude : Quantity

\(\phi_0\)

reference : Quantity

\(E_0\)

ecut : Quantity

\(E_{C}\)
