Three-dimensional distribution of known Centaurus group members in supergalactic coordinates centered on Cen A. The large red dot is Cen A, the large black dot is M 83, and the intermediate-size red dot is the late-type spiral NGC 4945. The small red dots are plane 1 dwarf satellite members, the blue dots plane 2 members from T15, the black dots are additional (non-plane) members of the Cen A group. The best-fitting planes 1 and 2 are illustrated by the red and blue disks, respectively. The smaller gray disk that stands almost orthogonally to the two satellite planes represents the dust lane of Cen A. The dashed black line corresponds to the line of sight toward Cen A. The green line connects the five regions in the tail of the tidally disrupted dwarf Cen A-MM-Dw3 where distances could be measured (Dw3, Dw3 S, Dw3 SE, Dw3 N, and Dw3 NW, Crnojević et al. 2016).
