Vector2 Acts::PixelSpacePointBuilder::computeVarianceZR	(	const GeometryContext &	gctx,
		const Surface &	surface,
		const Vector3 &	spacePoint,
		const SquareMatrix2 &	localCov )

Get z and r covariance from the local position and covariance.

Parameters

surface	The surface associated
spacePoint	The global position
localCov	The local covariance matrix

Returns

(z, r) components of the global covariance
