Figure 7 shows the position angle of each component plotted versus its radial offset from the center of the jet component, which we identify as the origin. Source C deviates from the straight line fit to the data by about 19$^\circ$. We assume that it is not part of the jet, but a separate entity from the jet, perhaps evidence of another nearby star. The straight-line fit of equation 7 to the remaining 9 sources gives parameters, $\theta_0 = -43^\circ \pm 4^\circ$ (the current PA of the jet), and $\alpha = \beta/v = 2.3 \pm 0.4$ degrees/arcsecond. For a distance of 2.9 kpc the value of $\alpha$ in the source frame is 9.2 $\times 10^{-19}$ radians/cm or 2.9 radians/pc. Since the jet seems to be precessing linearly with time, we assume that the precession period is much greater than the time scale of the flow. Note that we cannot solve separately for the precession rate and the ejection velocity. The shape of the jet at the current epoch, as determined by equations 5 and 6, is shown in Figure 8.

As noted before only two sources have significant proper motions, N-1 and S-1. Their motions are both in the transverse
