cds-question@unistra.frgalaxy-clustersspectroscopyredshiftedapparent-magnitudeWe present results of an H{alpha} survey in the rich cluster A 1689 at z=0.18, using the LDSS++ spectrograph on the Anglo-Australian Telescope (AAT). We obtained spectra covering redshifted H{alpha} at z=0.16-0.22, for 522 galaxies brighter than I=22.5, covering a field of 8.7x8.7arcmin^2^ (~1.1x1.1h^-1^Mpc at z=0.18). We securely detect H{alpha} emission in 46 of these galaxies; accounting for selection effects arising from sampling and cluster membership, we determine that 24+/-4 per cent of cluster members brighter than M_R_=-16.5+5logh are detected with H{alpha} flux greater than 4h^-2^x10^38^erg/s. From a Hubble Space Telescope mosaic covering 7.5x10.0arcmin, we determine morphologies for 199 galaxies brighter than I=21, and find that ~20 per cent of the cluster members are of type Sa or later. More than 90 per cent of cluster spirals show H{alpha} emission, compared with less than 10 per cent of E and S0 galaxies.2002MNRAS.335...10Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/335/10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/382/60 : BVR photometry in Abell 1689 (Duc+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/335/10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/335/10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/335/10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/335/10https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/335/10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/335/10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/335/10/table1 (Abell 1689 data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/335/10/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/335/10/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/335/10/table1?GETtext/xml+votable180.050000true197.85564167-1.343627780.0055555555555555566/26189https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/335/10?format=asciiOpticaldefaultJ/MNRAS/335/10/table1Abell 1689 datarecnoRecord number assigned by the VizieR team.
