cds-question@unistra.frgalaxiesvisible-astronomyastrometryapparent-magnituderadial-velocityWe have selected 36 loose groups of galaxies from Ramella et al. 1989, with at least five members, and with mean redshift cz>3200km/s. These groups all lie within the first two "slices" of the CfA redshift survey <VII/164> (RA between 8h and 17h, DE between 2655.5 and 38.5 degrees). For each of these groups, we define the "redshift-space neighbourhood" as a region centered on the group coordinates and delimited by a circle of projected radius 1.5xh^-1^ Mpc on the sky, and by a velocity interval of 3000km/s. Table 2 lists the positions, magnitudes, radial velocities (cz) and their errors, for the members of the groups published in RGH89. Coordinates and magnitudes are from Zwicky's CGCG <VII/4>. Unpublished redshifts are marked with an asterisk in the last column. Table 3 lists galaxies within 1.5Mpc (assuming H0=100) and +/-1500 km/s from the centers of the groups in redshift space. Magnitudes and positions are from the Zwicky-Nielsen merged catalog. Some coordinates are better coordinates than Zwicky's, some come from compilations of redshift data that we have used to complement our measurements. Unpublished redshifts are marked with an asterisk in the last column. In this table some galaxies appear twice because a few groups do overlap. We listed the galaxies in common under the labels of both groups.1995AJ....109.1458Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/109/1458CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/109/1458https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/109/1458http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/109/1458https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/109/1458https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/109/1458http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/109/1458GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/109/1458/table2 (The original group members in RGH89)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/109/1458/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/109/1458/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/109/1458/table2?GETtext/xml+votable180.050000true132.0465236.7650190.005555555555555556Cone search capability for table J/AJ/109/1458/table3 (Additional galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/109/1458/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/109/1458/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/109/1458/table3?GETtext/xml+votable180.050000true131.90166637.5988880.0055555555555555565/1238 2342 2595 2599 2608 7154 6/4961 4963-4964 4966-4967 4985 4987-4990 5095 5100 5103 5201 5204 5383 5389 5394-5395 5398 5400-5401 5404 5664-5665 5667 5669 5671 5680 8697 8699-8700 8702 9031 9037 9048 9121 9124 9126-9127 9132-9133 9135-9136 9144 9146 9357 9429 9431 9433 9435 9445-9447 9452 10317 10328 10342 10345 10348 10377 10379 10389-10391 10393-10395 10404 10417 10420 10439-10442 10445 10447 10456 10464 10469-10471 10517-10519 10531-10534 10536 10539-10540 10542 10560 10562-10563 28411-28412 28414 28461 28467 28473 28476 28492 28494 28512-28513 28515-28517 28519-28520 28522-28523 28526-28527 28555 28565 28567 28574 28576-28577 28597 28599 28608-28609 28612https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/109/1458?format=asciiOpticaldefaultJ/AJ/109/1458/table2The original group members in RGH89recnoRecord number assigned by the VizieR team.
