VizieR Online Data Catalog: HI data for 392 spiral galaxies (Bottinelli+, 1982)
Abstract
392 spiral galaxies with type Sb or later have been detected in the 21-cm line of neutral hydrogen with the Nancay radiotelescope, and among them 172 HI fluxes are obtained for the first time. The source of any possible bias has been carefully analyzed and only the Malmquist bias appears to be significant. In order to obviate this observational effect, the range of radial velocities has been properly truncated for all statistical studies. A mean value of each global parameter has been determined for each morphological type and compared to previous results.
