Dressler & Schectman bubble plot for the DSV test. Spatial distribution of the 126 cluster members, each indicated by a symbol: the larger the symbol, the greater the deviation |δ_i, V| of the local mean velocity from the global mean velocity. The blue thin and red thick circles indicate where the local mean velocity is smaller or larger than the global mean velocity. The diagram is centered on the center of the cluster and the large and small crosses indicate the BCG and LEDA 87445. The arrow indicates the direction of the velocity gradient, which points toward the region with high velocities.
