Detailed Description

The muon space point is the combination of two uncalibrated measurements one of them measures the eta and the other the phi coordinate.

In cases, without a complementary measurment the spacepoint just represents the single measurement and hence has a uncertainty into the other direction corresponding to the half-length of the measurement channel

◆ SpacePoint()

SpacePoint::SpacePoint	(	const xAOD::UncalibratedMeasurement *	primMeas,
		const xAOD::UncalibratedMeasurement *	secondMeas = `nullptr`
	)

In case of 2D measurements like sTgc-pads or BI-RPC strips we can directly take the covariance from the measurement itself. To indicate that the space point measures both, eta & phi coordinate set the secondary measurement to be the primary one
