Detailed Description

Objects used as position/flux anchors (e.g.

Gaia DR2 stars). Coordinate system should match that of the fittedStars these are associated with; typically the common tangent plane.

RefStars should have their proper motion and parallax corrections pre-applied, so that they are at the same epoch as is stored in Associations.

applyProperMotion()

Point lsst::jointcal::RefStar::applyProperMotion	(	const Point &	star,
		double	timeDeltaYears ) const

Apply proper motion correction to the input star, returning a star with PM-corrected coordinates and coordinate errors.

Star is returned unchanged if no proper motion data is available.

Parameters

star	The star to correct for this proper motion.
timeDeltaYears	The difference in time from the correction epoch to correct for, in years.

Returns

The star with corrected coordinates.
