1990ApJS...72..245S NORTHERN DWARF AND LOW SURFACE BRIGHTNESS GALAXIES. I. THE ARECIBO NEUTRAL HYDROGEN SURVEY STEPHEN E. SCHNEIDER Five College Astronomy Department; and Department of Physics and Astronomy, University of Massachusetts AND TRINH X. THUAN, CHRISTOPHER MAGRI, AND JAMES E. WADIAK Astronomy Department, University of Virginia Received 1989 April 3; accepted 1989 July 28 ABSTRACT Neutral hydrogen observations of a large sample of dwarf and other low surface brightness galaxies are presented. Nearly all galaxies classified in the Uppsala General Catalogue as dwarf, irregular, Sd-m, or later and in the declination range of the Arecibo telescope (-2^deg^ <= {delta} <= 38^deg^) have now been observed; here we report observations for 762 galaxies. About 40% of these galaxies have no previously published detections. In total, counting previous detections, over 90% of these late-type systems are detected at Arecibo. We have examined the galaxies for potential confusion with nearby galaxies, and we also derive substantially better sygnal-to-noise ratio measurements for many previously detected galaxies. Some general results of this survey are presented here, but the total data base of northern dwarf and low surface brightness galaxies, including a Green Bank survey of galaxies north of the Arecibo declination limit, will be examined in subsequent papers. Subject headings: galaxies: photometry - galaxies: redshifts - radio sources: 21 cm radiation
