H i velocity field contours derived from the high resolution cube on SDSS r-band band image (main panel). The velocity contours are plotted in 15 km s^-1 interval. The spatial resolution is 24.3′′  ×  21.0′′ with the beam size indicated by the ellipse. Inset panel: low resolution (47.1′′  ×  37.1′′), systemic velocity subtracted, H i velocity field for CIG 85. The systemic radial velocity is 2640 km s^-1. From white to black, the contours (in km s^-1) are 2570, 2580, 2590, 2600, 2610, 2620, 2630, 2650, 2660, 2670, 2680, 2690, 2700, 2710, 2720. The velocity resolution of the cube is  ~26 km s^-1.
