The observations have resulted in a catalogue with positions and magnitudes for 203 galaxies, complete at b_25 = 18.0, and radial velocities for 128 galaxies, 91 per cent complete at b_25 = 17.5. The cluster can be classified as type L because its galaxy distribution is highly flattened. It shows two strong concentrations: a main concentration, centred on the cluster brightest galaxy (a D galaxy) and coincident with the peak of X-ray emission, and a substructure around the second brightest galaxy (also a D galaxy). Most of the galaxies in this substructure seem to be bound to the second-brightest galaxy, forming a dynamical subunit inside the cluster. The extreme flattening of the cluster may at least partially be due to the presence of the substructure. The cluster also shows evidence for luminosity segregation, with the brightest galaxies being preferentially found in high galaxy density regions. Most of the luminosity segregation, however, is produced by galaxies associated with the two clumps around the D galaxies, suggesting that dynamical friction is effective in subclusters with low velocity dispersions and may be associated with the formation of D galaxies. The velocity dispersion of SC2008-57 is high, about 1200 km/s, but consistent with the observed X-ray luminosity. The cluster mass, derived using several estimators, is about 2.6 x 10^15 M_solar. Both the cluster mass and velocity dispersion may be overestimates due to the presence of the substructure. Notes: * In order to execute LaTeX of "t3.tex", a definition file "macros.tex" is needed in which at least definitions of \kmsec, \double, \etal are included. Comment from the author (SODRE L.): * The galaxy numbers in the Table 2 of the paper were not those from the Table 3. The correct numbers are 065, 086, 087, 097, 100, 120, respectively.1992MNRAS.259..233Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/259/233CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/259/233https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/259/233http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/259/233https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/259/233https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/259/233http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/259/233GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/259/233/table3 (Galaxy catalogue of the cluster of galaxies SC2008-57 (A3667))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/259/233/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/259/233/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/259/233/table3?GETtext/xml+votable180.050000true301.982765-56.2662330.0055555555555555566/45813 45962 45984 45985 45986https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/259/233?format=asciiOpticaldefaultJ/MNRAS/259/233/table3Galaxy catalogue of the cluster of galaxies SC2008-57 (A3667)DEB1950[56,57] declination (B1950)pos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
