Galaxy Groups Within 57 million light years (Mly) (v.2)

Revised 3D map of all galaxy groups within 57 million light years (Mly) that:

(1) are cataloged in: "Groups of galaxies within 80 Mpc. II. The catalogue of groups and group members." P Fouque, E Gourgoulhon, P Chamaraux, G Paturel, Astronomy and Astrophysics Supplement Series, 93:211-233 (1992) (LINK to the paper: https://adsabs.harvard.edu/full/1992A... ),

and

(2) are designated by a member galaxy cataloged in "50 Mpc Galaxy Catalog (50 MGC): Consistent and Homogeneous Masses, Distances, Colors, and Morphologies." David Ohlson, Anil C. Seth, Elena Gallo, Vivienne F. Baldassare, and Jenny E. Greene, The Astronomical Journal, 167:31 (18pp) (2024 January). (LINK to the paper: https://iopscience.iop.org/article/10... ).

Distances are from Ohlson et al. Regions are from Fouque et al. Table 1.

The base grid parallels the supergalactic plane, and lies 40.7 million light years (Mly) below the actual supergalactic plane. The actual supergalactic plane is visible as the second grid above the base grid.

Label abbreviations:
CenA-M83(N5128) = Centaurus A - Messier 83 group (designated by member galaxy Centaurus A = NGC 5128)
CVnI(M94) = Canes Venatici I Group or Messier 94 group
CVnII(M106) = Canes Venatici II Group or Messier 106 group
LeoI-M66 = Leo I group, Messier 66 subgroup
LeoI-M96 = Leo I group, Messier 96 subgroup
"N" in galaxy label = NGC (New General Catalog)
Scl(N253) = Sculptor Group (designated by member galaxy NGC 253)
UMaIS(N3718) = Ursa Major I South group (designated by member galaxy NGC 3718)
Virgo I cluster (designated by member galaxy Messier 87)
