Member Function Documentation

double GCTAModelIrfBackground::npred_roi_kern_phi::eval ( const double &  phi)
virtual

Kernel for azimuth angle integration of background model.

Parameters
[in]phiAzimuth angle around ROI centre (radians).

Computes

\[ B(\theta, \phi | E, t) \]

using

\[ {\rm detx} = \theta \cos \phi \]

\[ {\rm dety} = \theta \sin \phi \]

Todo:
Verify correct orientation of detx and dety with respect to phi

Implements GFunction.
