Uranus was tracked (using the'map16' technique) for an hour straddling transit through the south. Plots of the residuals against azimuth are shown below :

There are no large or significant structures (in azimuth or elevation) or steps (in elevation) that would indicate significant track model errors or transit effects, respectively. The rms scatters on the hour's worth of data are (0.7", 1.0") in (daz,del).
