Detailed Description

Photon flux normalized power law spectral model class.

This class implements a power law spectrum. The model is defined by

\[ S_{\rm E}(E | t) = {\tt m\_flux} \frac{{\tt m\_index}+1} {{\tt e\_max}^{{\tt m\_index}+1} - {\tt e\_min}^{{\tt m\_index}+1}} E^{\tt m\_index} \]

for \({\tt m\_index} \ne -1\) and

\[ S_{\rm E}(E | t) = \frac{{\tt m\_flux}} {\log {\tt e\_max} - \log {\tt e\_min}} E^{\tt m\_index} \]

for \({\tt m\_index} = -1\), where

\({\tt e\_min}\) is the minimum energy of an interval,
\({\tt e\_max}\) is the maximum energy of an interval,
\({\tt m\_flux}\) is the photon flux between \({\tt e\_min}\) and \({\tt e\_max}\), and
\({\tt m\_index}\) is the spectral index.
