RXC J0225 velocity and velocity dispersion profiles. Top left panel: 1σ uncertainty on the iVP (uneven continuous lines), VP (squares with 1σ error bars), and its LOWESS version (smooth continuous line). Bottom left panel: same as the top left panel, but for the iVDP and VDP. Top right panel: iVP for the red (filled region) and blue (empty region) populations, and the smoothed LOWESS VP (solid line for the red galaxies, dot-dashed for the blue ones). Bottom right panel: same as top right panel, but for the iVDP and VDP.
