Description:
Optical identifications are given of IRAS point sources: 312 sources in
a 304 square deg area centred on the South Galactic Pole, of which 148 are
identified with stars, 154 with galaxies and 10 are unidentified down
to 21st magnitude; 206 point sources in a 113 square deg area centred on
the Virgo cluster, of which 54 are identified with stars, 113 with
optically bright (B_J<16) galaxies, 32 with faint galaxies, and 7 are
apparently empty fields; (66, 114, 61) sources in the regions of
(Fornax, Hydra I, Coma) cluster of galaxies, of which (35, 48, 18) are
identified with stars, (43, 58, 41) with galaxies.
