Member Function Documentation

double GModelSpatial::circle_int_kern_rho::eval ( const double &  rho)
virtual

Kernel for spatial model radial integration.

Parameters
[in]rhoRadial distance from model centre (radians).
Returns
Integration kernel defined as

\[ \int_{\rho_{\rm min}}^{\rho_{\rm max}} K(\rho | E, t) d\rho \]

of a spatial model over a circular region. The eval() method computes

\[ K(\rho | E, t) = \sin \rho \times \int_{\omega} M(\rho, \omega | E, t) d\omega \]

where \(M(\rho, \omega | E, t)\) is the spatial model, \(\rho\) is the distance from the model centre, and \(\omega\) is the azimuth angle around the model centre.

Implements GFunction.
