Galaxies, IR Galaxies, radio Infrared sources Radio sources This catalog presents radio and optical identifications of extragalactic IRAS sources from the IRAS Faint Source Catalog |b| > 50{deg} (Moshir et al., 1989 Cat. <II/156>). Sources with flux density > 0.2 at 60 microns and with S_60_ > S_12_ were identified by position coincidence with radio sources stronger than 25 mJy and lying north of declination = 5{deg} on the Green Bank 4.85 GHz sky map. Published VLA maps, new 4.86 GHz VLA maps made with 15 arcsec resolution, and accurate optical positions were used to confirm 122 candidate identifications. This catalog contains a merged version of tables 1 and 2 from the paper.

IRAS Name of source (IRAS Faint Source Catalog) number=1 The "IRAS" column gives the IRAS Faint Source Catalog name in the format FHHMM.M+DDMM, where the letter F signifies that it is from the FSC, and the last digit of the RA field being the integer part of the RA seconds (i.e. the IAU-style truncation).
