Kernel for elliptical model integration over zenith angle.
| [in] | rho | Radial distance from model centre (radians). |
Computes the integration kernel
\[ K(\rho | E, t) = \sin \rho \times \int_{\omega} S_{\rm p}(\rho, \omega | E, t) \, PSF(\rho, \omega) d\omega \]
where \(\omega\) is the azimuth angle with respect to the model centre, counted counterclockwise from the vector connecting the model centre to the observed photon direction, and \(\rho\) is the radial distance from the model centre. \(S_{\rm p}(\rho, \omega | E, t)\) is the elliptical source model for a given true photon energy and photon arrival time, \(PSF(\rho, \omega)\) is the point spread function. The integration is over the \(\omega\) values that are comprised within the ellipse boundaries.
Implements GFunction.
