Top row: colored Legacy Survey grz-image (left-hand panel); map of Hα fluxes (middle panel); map of the ionized-gas velocity dispersions (right-hand panel). Bottom row: observed ionized-gas velocity field (left-hand panel); velocity field obtained with a tilted-ring model (middle panel); map of residuals after subtracting the model velocity field from the observed one (right-hand panel). The Hα contours are overlaid on the top middle, top right, and bottom right panels.
