   Fig. 9. - Rotation curve of NGC 7793. (a) Mean points at 5 arcsec and 20
 arcsec resolution. (b) Mean points at 20 arcsec resolution separately for east
 and west halves of galaxy. Velocity dispersion {sigma}_v_ (dashed), circular
 velocity V_c_ (dotted) of best fit two-component model, and calculated
 rotation curve V_r_ (solid line) are shown.
