HE 0433-1028. Top: 50′′ × 50′′V-band image (ESO-Danish 1.54 m telescope, NED, arbitrary intensity units) of the galaxy, the box size is 35′′ × 35′′. Middle: zoomed into the box region of unsharp masked version of the image (arbitrary intensity units) overlayed with contours of naturally weighted integrated ¹²CO(2–1) flux as in Fig. 2. Central region marked by box of size 10′′ × 10′′. Bottom: zoomed into inner 10′′ × 10′′ of unsharp masked image with contours of uniformly weighted integrated ¹²CO(2–1) flux as in Fig. 2.
