Constructor & Destructor Documentation

GCTAModelIrfBackground::npred_roi_kern_theta::npred_roi_kern_theta ( const GCTABackground *  bgd, const double &  logE, const GCTAInstDir &  roi_centre, const int &  iter  )

inline

Definition at line 96 of file GCTAModelIrfBackground.hpp.

Member Function Documentation

double GCTAModelIrfBackground::npred_roi_kern_theta::eval ( const double &  theta )

virtual

Kernel for offset angle integration of background model.

Parameters

[in]

theta

Offset angle from ROI centre (radians).

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.
