XSsrcut

class sherpa.astro.xspec.XSsrcut(name='srcut')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC srcut model: synchrotron spectrum, cutoff power law.

The model is described at [1].

Note

Deprecated in Sherpa 4.10.0

The breakfreq parameter has been renamed break_ to match the XSPEC definition. The name breakfreq can still be used to access the parameter, but this name will be removed in a future release.

alpha

The radio spectral index.

break_

The break frequency: approximately the frequency at which the flux has dropped by a factor of 10 from a straight power law.

norm

The 1 Ghz flux in Jy.
