Class Documentation

template<typename PixelT>
class SincCoeffs

A singleton to calculate and cache the coefficients for sinc photometry

Caching is only performed for circular apertures (because elliptical apertures are assumed to be generated dynamically, and hence not expected to recur). Caching must be explicitly requested for a particular circular aperture (using the ‘cache’ method).

Public Types

typedef afw::image::Image<PixelT> CoeffT

Public Static Functions

static void cache(float rInner, float rOuter)

Cache the coefficients for a particular aperture

The aperture is a circular annulus.
