For global reconstruction the position of spacepoints in the EMR needs to be known. Currently, the EMR reconstruction returns an x and y position in terms of bar number, and z in terms of the plane number. Conversion of this to a global coordinate could be done by globals by hard coding the position of the bar/plane based upon the Step 4 legacy geometry, and the errors on the positions, of half a bar width, can be included in the same way. Ideally, the position obtained from the EMR recon would instead be in the global system, as it is for tracker recon.
