H I morphology and kinematics: top set of images is NGC 3312; bottom is NGC 3314a. Left: DECam false color with H I contours at (1.2, 2.4, 4.8, 9.6) × 1020 cm−2 which corresponds to (4, 8, 16, 32) times the rms in a single 44 km s−1 channel. North is up and east is left, parallel to the figure axes. MeerKAT beam is the ellipse in the top right. Top right: H I total intensity gray scale. Red dashed and orange dot-dashed lines indicate the direction of motion or wind through the ICM as implied by the steep H I contours and the H I tail, respectively. Purple arrow indicates direction to center of the Hydra cluster. Middle right: H I intensity-weighted velocity map. Bottom: integrated H I profile. The ultra diffuse galaxy, UDG 32, recently reported by Iodice et al. (2021) is visible to the lower right of NGC 3314a, outside the H I contours.
