VizieR Online Data Catalog: Hα3 V. Coma cluster (Gavazzi+, 2015)
Abstract
Our sample is drawn from the 360-square degree region 10h<RA<16h; 24°<Dec<28°; 3900<cz<9000km/s, covering the Coma supercluster, including half of the Coma cluster. This region has been fully mapped by ALFALFA (Haynes et al., 2011, Cat. J/AJ/142/170), which provides us with a complete sample of HI selected galaxies, with HI masses as low as 109-9.5M⊙. The goal of the Hα3 survey is to follow up with Hα imaging observations the ALFALFA targets with high signal-to-noise ratio (typically S/N>6.5), and with consistent detection between two independent polarizations (code=1 sources in Haynes et al., 2011, Cat. J/AJ/142/170). We will refer to these targets as the HI or radio targets.
