Functions
std::unique_ptr< StarMatchList >	lsst::jointcal::matchSearchRotShift (BaseStarList &list1, BaseStarList &list2, const MatchConditions &conditions)
	searches a geometrical transformation that goes from list1 to list2.
std::unique_ptr< StarMatchList >	lsst::jointcal::matchSearchRotShiftFlip (BaseStarList &list1, BaseStarList &list2, const MatchConditions &conditions)
	same as above but searches also a flipped solution.
std::unique_ptr< StarMatchList >	lsst::jointcal::listMatchCollect (const BaseStarList &list1, const BaseStarList &list2, const AstrometryTransform *guess, double maxDist)
	assembles star matches.
std::unique_ptr< StarMatchList >	lsst::jointcal::listMatchCollect (const BaseStarList &list1, const BaseStarList &list2, double maxDist)
	same as before except that the transform is the identity
std::unique_ptr< AstrometryTransformLinear >	lsst::jointcal::listMatchupShift (const BaseStarList &list1, const BaseStarList &list2, const AstrometryTransform &transform, double maxShift, double binSize=0)
	searches for a 2 dimensional shift using a very crude histogram method.
std::unique_ptr< AstrometryTransform >	lsst::jointcal::listMatchCombinatorial (const BaseStarList &list1, const BaseStarList &list2, const MatchConditions &conditions=MatchConditions())

Detailed Description

Combinatorial searches for linear transformations to go from list1 to list2.

The following routines search a geometrical transformation that make two lists of stars to match geometrically as well as possible. They are used either to match two images of the same sky area, or an image with a catalogue. They assume that fluxes assigned to stars are actual fluxes, i.e. the brighter the star, the higher the flux. They however only rely on flux ordering, not values.
