Detailed Description

Exponential cut off power law spectral class.

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

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

where

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

Returns model energy flux between emin, emax

Parameters
[in]eminMinimum photon energy.
[in]emaxMaximum photon energy.
Returns
Energy flux (erg/cm2/s).

Computes

\[ \int_{\tt emin}^{\tt emax} S_{\rm E}(E | t) E \, dE \]

where

  • [emin, emax] is an energy interval, and
  • \(S_{\rm E}(E | t)\) is the spectral model (ph/cm2/s/MeV). The integration is done numerically.

Implements GModelSpectral.

double GModelSpectralExpPlaw::eval ( const GEnergy srcEng,
const GTime srcTime = GTime(),
const bool &  gradients = false 
) const
virtual

Evaluate function.

Parameters
[in]srcEngTrue photon energy.
[in]srcTimeTrue photon arrival time.
[in]gradientsCompute gradients?
Returns
Model value (ph/cm2/s/MeV).

Evaluates

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

where

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

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

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

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

\[ \frac{\delta S_{\rm E}(E | t)}{\delta {\tt m\_ecut}} = S_{\rm E}(E | t) \, \left( \frac{E}{{\tt m\_ecut}^2} \right) \]

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

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.
