Detailed Description

Super exponential cut off power law spectral class.

This class implements a power law spectrum with super exponential cut off. The model is defined by

\[ S_{\rm E}(E | t) = {\tt m\_norm} \left( \frac{E}{\tt m\_pivot} \right)^{\tt m\_index1} \exp \left( - \left( \frac{E}{\tt m\_ecut} \right)^{\tt m\_index2} \right) \]

where

\({\tt m\_norm}\) is the normalization or prefactor,
\({\tt m\_pivot}\) is the pivot energy,
\({\tt m\_index1}\) is the spectral index
\({\tt m\_ecut}\) is the cut off energy, and
\({\tt m\_index2}\) is the index of the cut off.

Parameters

[in]	srcEng	True photon energy.
[in]	srcTime	True photon arrival time.

Returns: Model value (ph/cm2/s/MeV).

Evaluates

\[ S_{\rm E}(E | t) = {\tt m\_norm} \left( \frac{E}{\tt m\_pivot} \right)^{\tt m\_index1} \exp \left( - \left( \frac{E}{\tt m\_ecut} \right)^{\tt m\_index2} \right) \]

where

\({\tt m\_norm}\) is the normalization or prefactor,
\({\tt m\_pivot}\) is the pivot energy,
\({\tt m\_index1}\) is the spectral index
\({\tt m\_ecut}\) is the cut off energy, and
\({\tt m\_index2}\) is the index of the cut off.

If the gradients flag is true the method will also compute the partial derivatives of the model with respect to the parameters using

\[ \frac{\delta S_{\rm E}(E | t)}{\delta {\tt m\_norm}} = \frac{S_{\rm E}(E | t)}{{\tt m\_norm}} \]

\[ \frac{\delta S_{\rm E}(E | t)}{\delta {\tt m\_index1}} = S_{\rm E}(E | t) \, \ln(E/{\tt m_pivot}) \]

\[ \frac{\delta S_{\rm E}(E | t)}{\delta {\tt m\_ecut}} = S_{\rm E}(E | t) \, \left( \frac{E}{{\tt m\_ecut}^{\tt m\_index2}} \right) \, \left(\frac{\tt m\_index2}{\tt m\_ecut}\right) \]

\[ \frac{\delta S_{\rm E}(E | t)}{\delta {\tt m\_index2}} = -S_{\rm E}(E | t) \, \ln \left(\frac{E}{\tt m\_ecut}\right)\, \left(\frac{E}{{\tt m\_ecut}^{\tt m\_index2}} \right) \]

\[ \frac{\delta S_{\rm E}(E | t)}{\delta {\tt m\_pivot}} = -S_{\rm E}(E | t) \, \left( \frac{\tt m\_index}{\tt m\_pivot} \right) \]

Todo:: The method expects that pivot!=0 and ecut!=0. Otherwise Inf or NaN may result. We should add a test that prevents using invalid values.

Returns: Energy.

Simulates a random energy in the interval [emin, emax] for an exponentially cut off power law. The simulation is done using a rejection method. First, a random energy within [emin, emax] is drawn from an power law distribution.
