cds-question@unistra.frgalaxy-clustersradial-velocityWe present new radial velocities for 306 bright (R<16) galaxies in a 77{deg}^2^ region of the Shapley supercluster, measured with the FLAIR-II spectrograph on the UK Schmidt Telescope. The galaxies we measured were uniformly distributed over the survey area, in contrast to previous samples which were concentrated in several rich Abell clusters. Most of the galaxies (230) were members of the Shapley supercluster: they trace out two previously unknown sheets of galaxies linking the Abell clusters of the supercluster. In a 44{deg}^2^ area of the supercluster excluding the Abell clusters, these sheets alone represent an overdensity of a factor of 2.0+/-0.2 compared to a uniform galaxy distribution. The supercluster is not flattened in the Declination direction as has been suggested in previous papers. Within our survey area the new galaxies contribute an additional 50% to the known contents of the Shapley supercluster, with a corresponding increase in its contribution to the motion of the Local Group.1999PASA...16..113Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/PASA/16.113CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/110/463 : Kinematics of the Shapley supercluster (Quintana+ 1995)J/A+AS/119/329 : VR photometry in the Shapley Supercluster (Slezak+, 1996)J/A+AS/120/357 : R magnitudes in four ESO fields (Infante+, 1996)J/A+AS/125/247 : Shapley Concentration galaxies velocities (Quintana+ 1997)J/MNRAS/296/599 : A3558 complex redshifts (Bardelli+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/PASA/16.113https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/PASA/16.113http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/PASA/16.113https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/PASA/16.113https://vizier.iucaa.in/viz-bin/votable?-source=J/other/PASA/16.113http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/PASA/16.113GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/PASA/16.113/table2 (*Galaxies observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/PASA/16.113/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/other/PASA/16.113/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/PASA/16.113/table2?GETtext/xml+votable180.050000true195.754978-36.6278930.005555555555555556Cone search capability for table J/other/PASA/16.113/table3 (*Abell clusters in the Shapley region)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/PASA/16.113/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/other/PASA/16.113/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/PASA/16.113/table3?GETtext/xml+votable180.050000true192.48419-36.755560.0055555555555555564/2737 5/10911 10952 10954-10958 10962 10976 10992 6/24848 24850 43451 43454-43455 43639 43732-43733 43736 43789-43791 43812 43814-43815 43836-43838 43842-43843 43874 43877 43883 43886 43891 43908-43910 43912 43914-43915 43920 43922 43924-43925 43927 43929 43931 43933 43939 43950 43972 43976-43977 43984 445862.4622242610829604e-19 3.264051565855503e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/PASA/16.113?format=asciiOpticaldefaultJ/other/PASA/16.113/table2*Galaxies observedrecnoRecord number assigned by the VizieR team.
