CRAB_HEGRA

ctao_cr_spectra.CRAB_HEGRA = PowerLaw(2.83e-11 1 / (TeV s cm2) * (E / 1.0 TeV)**-2.62)

A power law with normalization, reference energy and index.

Index includes the sign:

\[\Phi(E, \Phi_0, \gamma, E_\text{ref}) = \Phi_0 \left(\frac{E}{E_\text{ref}}\right)^{\gamma}\]

Attributes:

normalization: astropy.units.Quantity[flux]

\(\Phi_0\),

index: float

\(\gamma\)

e_ref: astropy.units.Quantity[energy]

\(E_\text{ref}\)
