Detailed Description

Broken power law spectral model class.

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

\[ S_{\rm E}(E | t) = k_0 \times \left \{ \begin{eqnarray} \left( \frac{E}{E_b} \right)^{\gamma_1} & {\rm if\,\,} E < E_b \\ \left( \frac{E}{E_b} \right)^{\gamma_2} & {\rm otherwise} \end{eqnarray} \right . \]

where \(k_0\) is the normalization or prefactor, \(\gamma_1\) is the spectral index before the break, \(\gamma_2\) is the spectral index after the break, and \(E_b\) is the break energy.

Parameters

[in]	emin	Minimum 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 analytically.

virtual

Parameters

[in]	srcEng	True photon energy.
[in]	srcTime	True photon arrival time.
[in]	gradients	Compute gradients?

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

Evaluates

\[ S_{\rm E}(E | t) = k_0 \times \left \{ \begin{eqnarray} \left( \frac{E}{E_b} \right)^{\gamma_1} & {\rm if\,\,} E < E_b \\ \left( \frac{E}{E_b} \right)^{\gamma_2} & {\rm otherwise} \end{eqnarray} \right . \]

where \(k_0\) is the normalization or prefactor, \(\gamma_1\) is the spectral index before the break, \(\gamma_2\) is the spectral index after the break, and \(E_b\) is the break energy.

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

\[ \frac{\delta S_{\rm E}(E | t)}{\delta k_0} = \frac{S_{\rm E}(E | t)}{k_0} \]

\[ \frac{\delta S_{\rm E}(E | t)}{\delta \gamma_1} = \left \{ \begin{eqnarray} S_{\rm E}(E | t) \, \ln(E/E_b) & {\rm if\,\,} E < E_b \\ 0 & {\rm otherwise} \end{eqnarray} \right . \]

\[ \frac{\delta S_{\rm E}(E | t)}{\delta \gamma_2} = \left \{ \begin{eqnarray} 0 & {\rm if\,\,} E < E_b \\ S_{\rm E}(E | t) \, \ln(E/E_b) & {\rm otherwise} \end{eqnarray} \right . \]

\[ \frac{\delta S_{\rm E}(E | t)}{\delta E_b} = k_0 \times \left \{ \begin{eqnarray} -S_{\rm E}(E | t) \, \left( \frac{\gamma_1}{E_b} \right) & {\rm if\,\,} E < E_b \\ -S_{\rm E}(E | t) \, \left( \frac{\gamma_2}{E_b} \right) & {\rm otherwise} \end{eqnarray} \right . \]

Todo:: The method expects that energy!=0. Otherwise Inf or NaN may result.
