The xy view of the best‐model kinematics. Contours show LOS velocities, where model velocities have been scaled to the observed range by multiplying by the scale factor of 100 km s−1 and adding 2800 km s−1 (the approximate systemic velocity). The local velocity dispersion is shown in gray scale, with regions of high dispersion darker and with a linear scale ranging from about 5 to 50 km s−1. The outer perimeter contours of this plot are not significant; this plot was made using MATLAB, which requires closed contours.
