Figure 1: Observed motion of T Tau Sb in the reference frame of T Tau Sa ( left) and T Tau N ( right). The dotted curves represent our best combined fit; each observation is connected to its modeled counterpart by a straight line. In the left-hand panel, the square indicates the fixed location of T Tau Sa and the dashed line connects it to the periastron. In the right-hand panel, filled diamonds represent the VLA measurements; the open diamonds indicate the 1998 VLA measurement excluded from the final fit and its fitted counterpart. In this panel, the dashed curve represents the motion of T Tau Sa.
