Integration kernel for GCTAEdisp2D::edisp_ereco_kern class.
- Parameters
-
[in] log10Ereco Log10 of reconstructed energy ( \(\log_{10}\) MeV).
- Returns
- Energy dispersion ( \((\log_{10}\) MeV \()^{-1}\)).
This method implements the function
\[ E_{\rm disp}(\log_{10} E_{\rm reco} | E_{\rm true}, \theta) = E_{\rm disp}(m | E_{\rm true}, \theta) \times \frac{\log 10 \times E_{\rm reco}}{E_{\rm true}} \]
which is the integration kernel needed for the GCTAEdisp2D::edisp_ereco_kern class. The class is used by GCTAEdisp2D::normalize_table() to integrate the energy dispersion information using
\[ \int_{\log_{10} E_{\rm reco}^{\rm min}}^{\log_{10} E_{\rm reco}^{\rm max}} E_{\rm disp}(\log_{10} E_{\rm reco} | E_{\rm true}, \theta) \, d(\log_{10} E_{\rm reco}) \]
Implements GFunction.
