A 21 cm survey of the Pisces-Perseus supercluster. III - The region north of +38 degrees

As part of a comprehensive survey of galaxies in the region of the Pisces-Perseus supercluster and its surroundings, 21-cm line observations obtained with the NRAO 91-m telescope are presented for 383 galaxies in the right ascension range from 22 to 10 hr and north of +38 deg declination. Recent improvements to the Green Bank receiver/feed system have dramatically raised detection rates at the distance of Pisces-Perseus (cz = +5000 km/s). The present study has contributed to double the number of known redshifts outside rich clusters in this section of the sky. The H I content of the current sample, as expressed in terms of the H I mass expected for a galaxy of the same optical size and morphology, matches the standard of normalcy established for isolated galaxies.
