LogParabola¶

class gammapy.spectrum.models.LogParabola(amplitude, reference, alpha, beta)[source]¶

Spectral log parabola model.

\[\phi(E) = \phi_0 \left( \frac{E}{E_0} \right) ^ { - \alpha - \beta \log{ \left( \frac{E}{E_0} \right) } }\]

Parameters:

amplitude : Quantity

\(\phi_0\)

reference : Quantity

\(E_0\)

alpha : Quantity

\(\alpha\)

beta : Quantity

\(\beta\)
