Left and middle: 3D illustration of H I clumps detected with CUPID, with different viewing angles for the left and middle panels. Blue ellipsoids represent the H I clumps, and red dots indicate the Hα emission regions detected in MUSE data. The size of the ellipsoids indicates the spatial size and velocity width of each clump, colour-coded by the H I flux. Right: 3D illustration of the natural-weighed VLA data produced by the 3D-Slicer package, with a fixed threshold cut applied and the same viewing angle as the middle panel.
