Three Dimensional structure of the Virgo Cluster
Z.Y. Shao

By using the Mixture Modal and radial velocity data from CfA
redshift catalogue, we resolve the substructures of the Virgo clus­
ter. Relative distances of three main subclusters (A, B, and W)
are determined by the Tully­Fisher galaxies, as well as LF, CMR
and FP of their member galaxies. Strong evidences have been
found to support that they are independent clusters, and the
Virgo area has a significant depth in the line­of­sight direction.
Additionally, the influence for calibrating the second rung of the
distance ladder are discussed in depth.
