B and V CCD Photometry of Southern, Extreme Late-Type Spiral Galaxies
Abstract
We present B and V CCD aperture photometry for a morphologically-selected sample of forty-nine southern, extreme late-type spiral galaxies. All objects are moderate-to-low surface brightness Local Supercluster field galaxies that were detected previously in HI surveys. Our sample features objects that have optical luminosities, optical sizes, and HI masses which are at the low end for spiral galaxies. These objects are not a new class of galaxy, but are examples of a common type of spiral galaxy that has been under-represented in nearby galaxy samples. (Abridged).
