Our sample of cluster galaxies studied following the methods explained in Sect. 3 and presented in the same order as in Table A.1. Col. 1: z-band Suprime-Cam image centered on the target; Col. 2: residuals after subtracting the 2D model of the galaxy; Col. 3: synthetic velocity field after fitting the simulated rotation curve to the observed curve; Col. 4: rotation curve (black dots) in the observed frame and the simulated rotation curve (red line). The black solid parallel lines in the panels in Cols. 1 and 3 depict the position of the edges of the slit.
