Detailed Description

Flux normalized power law spectral model class.

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

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

for ${\tt m\_index} \ne -1$ and

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

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,
${\tt m\_integral}$ is the integral flux between ${\tt e\_min}$ and ${\tt e\_max}$ , and
${\tt m\_index}$ is the spectral index.

$\frac{\delta S_{\rm E}(E | t)}{\delta {\tt m\_integral}} = \frac{S_{\rm E}(E | t)}{{\tt m\_integral}}$

$\frac{\delta S_{\rm E}(E | t)}{\delta {\tt m\_index}} = S_{\rm E}(E | t) \, \left( \frac{1}{{\tt m\_index}+1} - \frac{\log({\tt e\_max}) {\tt e\_max}^{{\tt m\_index}+1} - \log({\tt e\_min}) {\tt e\_min}^{{\tt m\_index}+1}} {{\tt e\_max}^{{\tt m\_index}+1} - {\tt e\_min}^{{\tt m\_index}+1}} + \ln(E) \right)$

$\frac{\delta S_{\rm E}(E | t)}{\delta {\tt m\_index}} = S_{\rm E}(E | t) \, \ln(E)$

for ${\tt m\_index} = -1$ .

No partial derivatives are supported for the energy boundaries.
