Optical identifications of IRAS point sources - The Fornax, Hydra I and Coma clusters
Optical identifications are presented for 66 IRAS point sources in theregion of the Fornax cluster of galaxies, 106 IRAS point sources in theregion of the Hydra I cluster of galaxies (Abell 1060), and 59 IRASpoint sources in the region of the Coma cluster of galaxies (Abell1656). Eight other sources in Hydra I do not have optical counterpartsand are very probably due to IR cirrus. Twenty-three (35 percent) of theFornax sources are associated with stars and 43 (65 percent) withgalaxies; 48 (42 percent) of the Hydra I sources are associated withstars and 58 (51 percent) with galaxies; 18 (31 percent) of the Comasources are associated with stars and 41 (69 percent) with galaxies. Thestellar and infrared cirrus surface density is consistent with thegalactic latitude of each field.
