cds-question@unistra.frgalaxy-clustersapparent-magnituderedshiftedWe present the first results of an optical follow-up of X-ray bright clusters of galaxies located between 0.15<=z<=0.31: B and R photometry as well as medium resolution spectroscopy of the galaxies. The cluster studied here - A1300 - is found to have a redshift of 0.3072 and a velocity dispersion of 1210km/s, based on 52 cluster members. Structures are observed in the galaxy number counts but the velocity histogram shows no significant departure from a Gaussian distribution.1997A&AS..124..283Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/124/283CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/124/283https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/124/283http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/124/283https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/124/283https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/124/283http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/124/283GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/124/283/table4 (Spectroscopic analysis of A1300)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/124/283/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/124/283/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/124/283/table4?GETtext/xml+votable180.050000true173.0569-19.89290.005555555555555556https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/124/283?format=asciiOpticaldefaultJ/A+AS/124/283/table3Photometric analysis of A1300recnoRecord number assigned by the VizieR team.
