Abstract

We are in the midst of obtaining 21 cm observations of late-type (Sdm through ImV, including BCD) dwarf galaxies in the Virgo Cluster, selected from the Binggeli, Sandage and Tammann catalog (1985, in press). To date, we have observed 174 of these objects; the sample is nearly complete to BT = 17.0. 114 have been detected, and 37 of the strongest emitters have been mapped at 119 spacing to determine HI diameters and rotation curves.
