cta_psf_diffuse_kern_phi()

cta_psf_diffuse_kern_phi::cta_psf_diffuse_kern_phi ( const GModelSpatial * model, const GMatrix * rot, const GEnergy & srcEng, const GTime & srcTime, const double & sin_delta, const double & cos_delta )

Member Function Documentation

eval()

double cta_psf_diffuse_kern_phi::eval ( const double & phi )

virtual

Kernel for map integration of spatial model.

Parameters

[in]

phi

Azimuth angle (radians).

Returns

Spatial model value.

Computes the value of the spatial model at the position (delta,phi) given in point spread function coordinates. The transformation from point spread function coordinates into sky coordinates is done using a rotation matrix that is pre-computed on entry.

Implements GFunction.
