Scientific paper

Radio identifications of galaxies in the Uppsala General Catalogue of Galaxies with δ < +82° were made from the Green Bank 1400 MHz sky maps. Every source having peak flux density SP ≥ 150 mJy in the ≈12 arcmin FWHM map point-source response and position <5 arcmin in both coordinates from the optical position of any UGC galaxy was considered a candidate identification to ensure that very extended (up to 1 Mpc) and asymmetric sources would not be missed. Maps in the literature or new 1.49 GHz VLA C array maps made with 18 arcsec resolution were used to confirm or reject candidate identifications. The resulting list of 176 confirmed identifications should be complete, reliable, and suitable for statistical investigations of radio emission from nearby (D < 300 Mpc for H0 = 50 km s-1Mpc-1) galaxies of all morphological types. Three criteria for distinguishing starbursts from monsters on the basis of radio and far-infrared continuum only are given and used to classify the dominant energy sources in the N = 176 confirmed galaxy identifications.
