		Cat2 const &	cat2,

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

radius	match radius

std::vector< Match< typename Cat1::Record, typename Cat2::Record > > lsst::afw::table::unpackMatches	(	BaseCatalog const &	matches,
		Cat1 const &	cat1,
		Cat2 const &	cat2 )

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,
		ReferenceCollection &	refList )

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
[in,out]	refList	Collection of reference objects. The schema must have three fields: "coord": a field containing an ICRS lsst::afw::SpherePoint; this field is read "centroid": a field containing lsst::geom::Point2D; this field is written "hasCentroid": a flag; this field is written

Exceptions

lsst::pex::exceptions::NotFoundError

if refList's schema does not have the required fields.

updateSourceCoords()

template<typename SourceCollection >

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

Update sky coordinates in a collection of source objects.

Template Parameters

SourceCollection

Type of sequence of sources, e.g. lsst::afw::table::SourceCatalog or std::vector<std::shared_ptr<lsst::afw::table::SourceRecord>>

Parameters

[in]	wcs	WCS to map from pixels to sky
