Abstract

We present long-slit Hα observations of 50 low surface brightness galaxies. Of these, 36 are of sufficient quality to form rotation curves. These data provide a large increase in the number of low surface brightness galaxies for which accurate rotation curves are available. They also represent an order-of-magnitude improvement in spatial resolution over previous 21 cm studies (1″-2″ instead of 13″-45″). The improved resolution and accuracy of the data extend and strengthen the scientific conclusions previously inferred from 21 cm data.
