zrange()

void zrange	(	double	nsigma,
		double	fence,
		double &	zed,
		double &	zedMinus,
		double &	zedPlus,
		const SG::ReadCondHandleKey< InDet::BeamSpotData > &	bs,
		const EventContext &	ctx
	)

0x4 is the online flag - 0x7 is presumably converged online

technically, updating the z position itself should not be needed
