Position-velocity diagrams along the galaxy major axis for all PUMA systems that show i) a well-defined velocity gradient along the major axis and ii) a peak in the velocity dispersion diagram close to the position of the nucleus. These two conditions provide initial evidence for rotation-dominated kinematics. All systems whose gas (stellar) kinematics satisfy the two conditions are marked with a blue (red) check mark in the top-right corner of the velocity dispersion panel; on the contrary, the systems that do not satisfy at least one of the two conditions are marked with a cross symbol; more uncertain kinematics are marked with a question mark. The systems for which neither the gas nor the stellar components satisfy the two conditions are not reported in this figure. Line velocity centroids and line widths of narrow Hα, total Hα, and stars are reported for each target, as labelled. See Fig. 4 for further details about the individual panels.
