Collect stars from an external reference catalog and associate them with fittedStars.

Parameters

	refCat	The catalog of reference sources
[in]	matchCut	Separation radius to match fitted and reference stars.
	fluxField	The field name in refCat to get the flux from.
	refFluxMap	fluxes per filter of corresponding refCat objects (can be empty)
