Scientific paper

The authors report the results of the second part of a survey of the 1400 MHz radio continuum radiation from dwarf galaxies. This work completes a survey of low surface brightness dwarf galaxies (LSBG) in the Uppsala General Catalog (UGC) (Nilson 1973), and in the Catalog of Selected non-UGC Galaxies (Nilson 1974), which are brighter than magnitude 17 and are in the Arecibo Observatory declination range (0° < δ < 38°). Detailed measurements of six fields with possible detections from the first part are presented. The overall detection rate above 10 mJy for the authors' sample of dwarf galaxies is less than about 3%, lower than the equivalent detection rate for blue compact dwarf galaxies (BCDG) studied by Klein et al. (1984). The results indicate that, on average, for a given optical luminosity LSBG are weaker radio emitters than BCDG.
