std::ostream & lsst::jointcal::operator<<	(	std::ostream &	stream,
		const StarMatchList &	starMatchList )

A std::list of star matches,.

To be used as the argument to AstrometryTransform::fit routines. There is as well a StarMatch::fit routine which fits a polynomial by default, although the transform may be user-provided. The StarMatchList::refineTransform is a convenient tool to reject outliers. Given two catalogs, one can assemble a StarMatchList using utilities such as listMatchCollect. StarMatchList's have write capabilities. NStarMatchList is a generalization of this 2-match to n-matches.
