The Aquarius superclusters. II. Spectroscopic and photometric data. Caretta C.A., Maia M.A.G., Willmer C.N.A. <Astron. J., 128, 2642-2651 (2004)> =2004AJ....128.2642C
ADC_Keywords: Clusters, galaxy ; Redshifts ; Galaxies, photometry Keywords: galaxies: clusters: general - galaxies: distances and redshifts - surveys Abstract: We present spectroscopic and photometric data for 920 galaxies selected in 68 fields of the Aquarius Cluster Catalog. Typically, the 15 brightest candidate members with magnitudes in the range 16<bJ<21 were selected for observations, and ∼71% turn out to be cluster members. Using the new redshift determinations, we assign galaxies to groups and clusters, and by including data from the literature we calculate systemic velocities and velocity dispersions for 74 clusters, each with redshifts measured for at least six individual galaxies. Description: We carried out 25 observing runs between 1994 and 2000, using three telescopes: the 1.52m telescope of La Silla Observatory (ESO, Chile), the 1.60m telescope of Observatorio do Pico dos Dias (OPD/LNA, Brazil), and the 2.15m telescope of Complejo Astronomico El Leoncito (CASLEO, Argentina).
