¹²CO velocity map images of the discs created with the bettermoments quadratic method (Teague & Foreman-Mackey 2018). A 4-sigma clipping process was applied to all images. The FWHM beam size is shown in the bottom left of each panel. Each image is scaled so that the maximum and the minimum are equal to the systemic velocity of the primary target ±2 km s⁻¹. Green contours show five times the rms of the continuum emission. The components of the systems are labelled. The label for any undetected secondary components in the continuum emission is not shown.
