LogParabola

class pyirf.spectral.LogParabola(normalization, a, b, e_ref=<Quantity 1. TeV>)

Bases: object

A log parabola flux parameterization.

\[\Phi(E, \Phi_0, \alpha, \beta, E_\text{ref}) = \Phi_0 \left( \frac{E}{E_\text{ref}} \right)^{\alpha + \beta \cdot \log_{10}(E / E_\text{ref})}\]

Attributes:

a: float

\(\alpha\)

b: float

\(\beta\)

e_ref: astropy.units.Quantity[energy]

\(E_\text{ref}\)
