Left panel: the Hermite velocity field (grayscale with black contours) with the best-fitting model velocity field for the inner disk overlaid. Contours are as in Fig. 6 with a contour spacing of 25 km s-1. Right panel: residual velocity field derived by subtracting the model from the observations. The thick black contour shows the 0 km s-1 level. The thin black contour + 10 km s-1, the thin white contour −10 km s-1. The maximum and minimum values found are + 16 and −16 km s-1, respectively.
