Radial peculiar velocities of galaxies in a supergalactic slice with 15 Mpc thickness. Radial peculiar velocities are grouped (averaged) using the groups obtained with a FoF algorithm (upper panels) and the Bayesian group finder (lower panels). A red dot means that the peculiar velocity is positive while a blue dot means that it is negative, the dot size is proportional to the absolute value of the radial peculiar velocity. Smaller panels on the right-hand side show two specific regions, Coma and Centaurus cluster regions, to highlight some of the differences in detail.
