cds-question@unistra.frgalaxy-clustersredshiftedradial-velocityWe present the results of a redshift survey of intercluster galaxies in the central region of the Shapley Concentration supercluster, aimed at determining the distribution of galaxies in between obvious overdensities. Our sample is formed by 442 new redshifts, mainly in the b_J_ magnitude range 17-18.8. Adding the data from our redshift surveys on the A3558 and A3528 complexes, which are close to the geometrical centre of this supercluster, we obtain a total sample of ~2000 radial velocities. The average velocity of the observed intercluster galaxies in the Shapley Concentration appears to be a function of their ({alpha}, {delta} position, and it can be fitted by a plane in the three dimensional space ({alpha}, {delta}, v): the distribution of the galaxy distances around the best-fitting plane is described by a Gaussian with dispersion 3.8h^-1^Mpc.2000MNRAS.312..540Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/312/540CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/296/599 : A3558 complex redshifts (Bardelli+, 1998)J/MNRAS/320/387 : The A3528 complex (Bardelli+, 2001)J/A+AS/125/247 : Shapley Concentration galaxies velocities (Quintana+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/312/540https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/312/540http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/312/540https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/312/540https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/312/540http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/312/540GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/312/540/table2 (Redshift data for the intercluster sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/312/540/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/312/540/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/312/540/table2?GETtext/xml+votable180.050000true194.4989167-29.54552780.0055555555555555565/10981-10982 10988 10992-10993 10998 6/43838-43839 43873 43880 43882-43883 43886 43911 43917-43919 43921-43923 43934-43935 43941-43943 43948-43949 43956 43960 43981-43983 43986 43990 43996 44004-44005 44007 44016 44018https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/312/540?format=asciiOpticaldefaultJ/MNRAS/312/540/table2Redshift data for the intercluster sampleNotesNotesmeta.notecharrecnoRecord number assigned by the VizieR team.
