Rotating disks in the merging dwarfs. Top panel: Rotational velocity of each separated component derived using. Both components show a similar radial gradient of rotational velocity by tracing the Hα emission line. We note that results beyond ∼5 arcsec are excluded from our discussion as they are derived from fits over spaxels with S/N < 15. Bottom panel: Enclosed dynamical mass of each component calculated at a given radius using the rotation curves estimated by ^3DBAROLO, assuming spherical symmetry. Each mass is the enclosed at a given radius. The rotational velocity map of each component is shown inside boxes. In each map, the assumed kinematical centre of the galaxies is marked. The green line represents the V_rot = 0 km s⁻¹ isoline of each velocity map.
