Channel maps based on a natural-weighted VLA data cube of VCC 693. The 3.4 km s−1 velocity channels were binned here to 10 km s−1. The blue, green, and red contour indicate 2, 4, and 6σ, where σ= 5.2 mJy beam−1 is the rms noise of the data cube. The beam size is indicated in the bottom left of the first panel. The heliocentric velocity is indicated to the top left in each panel.
