Phase-space diagrams of the NGC 2750 system. Left: Spatial distribution of known members (circles) and candidates (squares) coloured (when measurements are available) according to their difference in line-of-sight velocity from that of the central host. Right: line-of-sight velocity difference as a function of the on-sky distance along the major axis (d_Major); the solid black lines is the best fit of the rotational model with the 1σ confidence interval, while the discontinuous vertical lines represent the d_Major values of the DGCs.
