The study of the ratio of dark-to-luminous matter in spiral galaxies has been the subject of several recent studies (Bahcall 1983; Casertano 1983; Carignan and Freeman 1985; van Albada et al. 1985; Carignan 1985). These studies have been possible because of the large number of high sensitivity HI observations which became available in the last few years, allowing to probe the halo potential to very large galactocentric distances. In the case of NGC 3198 (van Albada et al. 1985), it was even possible to derive the rotation curve out to 11 disc scale lengths. One of the important questions, forming the motivation for this type of work, is whether the ratio of dark-to-luminous matter is a function of galaxy mass and/or luminosity.
