H I morphology and kinematics of NGC 3314b. Left: DECam false color image with H I total intensity 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 (NGC 3311). Middle right: H I intensity-weighted velocity map. Bottom: integrated H I profile. NGC 3314b is at ∼4700 km s−1; the emission below ∼3000 km s−1 is H I associated with NGC 3314a in the foreground (see Fig. 3).
