Spatial distribution of the 143 cluster member galaxies. The larger the circle, the larger is the deviation of the local mean velocity, as computed on the galaxy and its 10 neighbors, from the global mean velocity. The blue thin-line and red thick-line circles show where the local value of mean velocity is lower or higher than the global value. The green dashed ellipses indicate the regions of the subgroups detected by Nikogossyan et al. (1999; see their Fig. 13, the subgroup No. 2 is outside of our field). The center is fixed on the NGC 547 galaxy.
