Up: HI observations of galaxies


2 Sample selection

Whilst these two regions have previously been surveyed in H I (Gavazzi 1987; Hoffman et al. 1996, and reference therein), H I data are still lacking for many galaxies. The present project is aimed at completing the H I observations of galaxies with available redshift measurements. The inclusion of galaxies detected in the UV (at 2000 Å) was meant as a first step towards the construction of a UV-selected galaxy sample complete in H I. Most of these are early types (E/S0), but with blue colors, and our aim was to see whether H I is present in them.

- Sample 1: Virgo cluster: 8 spirals from the VCC catalogue (Binggeli et al. 1985), 6 brighter than $B_{\rm T}=15$ and 3 of $B_{\rm T}$ $\sim$ 16, as well as 5 early-type galaxies;

- Sample 2: Coma/A1367 supercluster: 25 galaxies, practically all spirals brighter than $B_{\rm T}=15.7$, and 6 galaxies detected in the UV.

Basic optical data for the galaxies observed in H I are listed in Table 1. The coordinates listed were used as the actual pointing centres for the Nançay radio telescope observations. Morphological types were taken from the on-line LEDA and NED databases; blue apparent magnitudes, $B_{\rm T}$, isophotal blue diameters, D25, and optical velocities and their uncertainties, $V_{\rm opt}$, were taken from the mean data catalogued in LEDA.
