Compute all tuples (s1,s2,d) where s1 belings to cat1, s2 belongs to cat2 and d, the distance between s1 and s2, is at most radius.

If cat1 and cat2 are identical, then this call is equivalent to matchRaDec(cat1,radius). The match is performed in ra, dec space.

This is instantiated for Simple-Simple, Simple-Source, and Source-Source catalog combinations.

Parameters

cat1	first catalog
cat2	second catalog
radius	match radius
mc	how to do the matching (obeys MatchControl::findOnlyClosest)

		Cat2 const &	cat2,

		bool	closest
	)

Compute all tuples (s1,s2,d) where s1 belings to cat1, s2 belongs to cat2 and d, the distance between s1 and s2, is at most radius.

If cat1 and cat2 are identical, then this call is equivalent to matchRaDec(cat1,radius). The match is performed in ra, dec space.

Deprecated:: . Use the matchRaDec(..., MatchControl) version

Parameters

[in]	cat1	first catalog
[in]	cat2	second catalog
[in]	radius	match radius
[in]	closest	if true then just return the closest match

This is instantiated for Simple-Simple, Simple-Source, and Source-Source catalog combinations.

	)

Reconstruct a MatchVector from a BaseCatalog representation of the matches and a pair of catalogs.

Note: The first and second catalog arguments must be sorted in ascending ID order on input; this will allow us to use binary search algorithms to find the records referred to by the match table.

If an ID cannot be found in the given tables, that pointer will be set to null in the returned match vector.

Parameters

[in]	matches	A normalized BaseCatalog representation, as produced by packMatches.
[in]	cat1	A CatalogT containing the records used on the 'first' side of the match, sorted by ascending ID.
[in]	cat2	A CatalogT containing the records used on the 'second' side of the match, sorted by ascending ID. May be the same as first.

This is instantiated for Simple-Simple, Simple-Source, and Source-Source catalog combinations.

◆ updateRefCentroids()

template<typename ReferenceCollection >

void lsst::afw::table::updateRefCentroids	(	geom::SkyWcs const &	wcs,

Update centroids in a collection of reference objects.

Template Parameters

RefCollection Type of sequence of reference objects, e.g. lsst::afw::table::SimpleCatalog or std::vector<std::shared_ptr<lsst::afw::table::SimpleRecord>>

Parameters

[in]	wcs	WCS to map from sky to pixels
