Notes. Galaxies in the overlapping regions that satisfy the membership criteria of two different structures are assumed to be members of the smallest structure for clusters C, W, W′, M, and the LVC clouds. Those in the overlapping region between clusters A and B are assigned to the substructure whose centre is closest to the galaxy.

(a)

Radius used to identify the different substructures. For clusters A and B, this corresponds to the r200 radius from Ferrarese et al. (2012).

(b)

Only one object within the VESTIGE footprint with 3000 < vhel < 3500 km s−1 is clearly detected by VESTIGE, VCC 357 (vhel = 3008 km s−1), here considered as a Virgo cluster member.

(c)

Mean distance of each single substructure.
