Combined astrometric (upper panel) and spectroscopic (lower panel) orbit for WDS 18070+3034AB. The solid line in the lower panel corresponds to the predicted velocity curve for A. Individual measurements for the visual orbit were taken from the WDS database at USNO. In the lower panel, triangles correspond to CORAVEL data, squares to velocities from Abt & Willmarth (2006), diamonds to Tokovinin & Smekhov (2002), and double triangles to the old radial velocities collected by Kamper & Beardsley (1986).
