Function Documentation

SourceMatchVector lsst::afw::table::matchXy(SourceCatalog const &cat, double radius, bool symmetric)

Compute all tuples (s1,s2,d) where s1 != s2, s1 and s2 both belong to cat, and d, the distance between s1 and s2, in pixels, is at most radius. The match is performed in pixel space (2d cartesian).

Parameters

• [in] cat: the catalog to self-match

• [in] radius: match radius (pixels)

• [in] symmetric: if cat to true symmetric matches are produced: i.e. if (s1, s2, d) is reported, then so is (s2, s1, d).
