An infrared and optical study of bright IRAS point sources of minimum apparent temperature
A sample of 170 sources from the IRAS Point Source Catalog (PSC) having === b === ≥ 40°, 100μm flux F₄ ≥ 2.5 Jy, and upper limit fluxes at 12, 25 and 60μm was studied on POSS and ESO photographic plates. 151 of these sources are identified as 'infrared cirrus,' thirteen as galaxies, and on...
