Member Function Documentation

double GCTAModelAeffBackground::npred_roi_kern_theta::eval ( const double &  theta)
virtual

Kernel for offset angle integration of effective area background model.

Parameters
[in]thetaOffset angle from ROI centre (radians).
Returns
Integration kernel value.

Computes

\[ K(\rho | E, t) = \sin \theta \times \int_{0}^{2\pi} B(\theta,\phi | E, t) d\phi \]

where \(B(\theta,\phi | E, t)\) is the background model for a specific observed energy \(E\) and time \(t\).

Implements GFunction.
