TitleH i Detection Survey of a Complete Magnitude-limited Sample of Dwarf Irregular Galaxies in the Virgo Cluster Area
AuthorsHoffman, G. Lyle; Helou, George; Salpeter, E. E.; Glosson, John; Sandage, A.

AbstractNew single-beam Arecibo H I observations of 298 late-type galaxies in the Virgo Cluster drawn mostly from the new catalog of Binggeli, Sandage, and Tammann (1985) are presented. Two hundred seventeen of these constitute a magnitude-limited 'complete sample' of such galaxies, types Sdm through Im and BCD. Sixty-one percent of this 'complete sample' was detected, greatly enhancing the store of redshifts and H I masses for such galaxies in the Virgo Cluster. For detected galaxies, heliocentric velocities, 50 percent profile widths, and single-beam fluxes are presented. For those that escaped detection, upper limits are computed to the flux appropriate to the redshift range (-600 to +3000 km/s).
