We have extended the discussion of Paper II (Ekholm et al., 1999A&A...351..827E) to cover also the backside of the Local Supercluster (LSC) by using 96 galaxies within Θ<30° from the adopted centre of LSC and with distance moduli from the direct B-band Tully-Fisher relation. In order to minimize the influence of the Malmquist bias we required logV_max>2.1 and σ_BT<0.2mag. We found out that if R_Virgo<20Mpc this sample fails to follow the expected dynamical pattern from the Tolman-Bondi (TB) model. When we compared our results with the Virgo core galaxies given by Federspiel et al. (1998ApJ...495..115F) we were able to constrain the distance to Virgo: R_Virgo=20-24Mpc. When analyzing the TB-behaviour of the sample as seen from the origin of the metric as well as that with distances from the extragalactic Cepheid PL-relation we found additional support to the estimate R_Virgo=21Mpc given in Paper II. Using a two-component mass-model we found a Virgo mass estimate M_Virgo=(1.5-2)M_virial, where Mvirial_=9.375x1014^M_☉ for R_Virgo=21Mpc. This estimate agrees with the conclusion in Paper I (Teerikorpi et al., 1992A&A...260...17T). Our results indicate that the density distribution of luminous matter is shallower than that of the total gravitating matter when q₀≤0.5. The preferred exponent in the density power law, α≃2.5, agrees with recent theoretical work on the universal density profile of dark matter clustering in an Einstein-deSitter universe (Tittley & Couchman, 1999, in press).
