double cta_psf_radial_kern_rho::eval ( const double & rho )

virtual

Kernel for radial model integration over zenith angle.

Parameters

[in] rho Radial distance from model centre (radians).

Returns: Integration kernel.

Computes the integration kernel

\[ K(\rho | E, t) = \sin \rho \times S_{\rm p}(\rho | E, t) \times \int_{\omega} PSF(\rho, \omega) d\omega \]

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. \(S_{\rm p}(\rho | E, t)\) is the radial source model for a given true photon energy and photon arrival time, \(PSF(\rho, \omega)\) is the point spread function.

Implements GFunction.
