Member Function Documentation

eval()

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

virtual

Kernel for spatial model radial integration.

Parameters

[in]

rho

Radial 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.
