Peculiar velocities and bulk flow directions in Galactic coordinates (Aitoff projection). Clusters in the SMAC survey are indicated by open circles (inflowing) or asterisks (outflowing), with symbol size proportional to peculiar velocity. The direction of the SMAC bulk flow is indicated by the large "S," while the dots show 1000 directions drawn from the bulk flow error ellipsoid. Important directions are indicated: the motion of the Local Group (LG), the motion of the Lynden‐Bell et al. (1988) sample (7S), the bulk flow of LP, the motion of the Riess et al. (1997) Type Ia supernova sample (R), the Shapley concentration (SC), the Horologium‐Reticulum supercluster (HR), and the predicted motion of the LG from X‐ray clusters (X) (Plionis & Kolokotronis 1998). The bulk flow of Dale et al. (1998) is small and consistent with zero. Consequently, its direction is not meaningful and has not been plotted here.
