Neutral hydrogen observations with the 100-m Effelsberg radio telescope are presented for 268 spiral galaxies from the Revised Flat Galaxy Catalog. Fluxes, radial velocities and line widths are given for 121 detected galaxies, as well as search parameters for 147 undetected objects. Most of the detected galaxies are late type (Sbc – Sdm) spirals with a mean ratio of 2.5 in solar units. (M25 is the total mass within the isophote) and a mean hydrogen mass fraction . Correlations between global parameters are discussed briefly. A comparison with a sample of nearby galaxies (within 10 Mpc) demonstrates the validity of the same linear relation between the optical luminosity (LB) and the linear diameter (A25) down to the smallest galaxies.
Key words: galaxies: fundamental parameters / galaxies: spiral / galaxies: general
