Member Function Documentation

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

Kernel for circular sky region radial integration.

Parameters
[in]rhoRadial distance from region 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 region centre, and \(\omega\) is the position angle with respect to the connecting line between the region centre and the direction on the sky.

Implements GFunction.
