Plot of measurements for 73 Leo made with the NPOI. The ellipse represents the final (i.e., combined) orbit (Section 3). The location of the primary is at the origin; the relative positions of the secondary are plotted together with their error ellipses. The vector from the origin indicates the periastron point. The scales (in milliarcseconds, mas) in R.A. and decl. are marked on the bottom and left axes, respectively.
