Description we propose to use phot to carry out measurements at wavelengths of 11.5, 60 and 160um (11.5, 60, 135 and 200 for the brightest objects) of a complete sub-sample of optically selected bright quasars taken from two recently completed multicolour (u,b,v,r,i) quasar surveys. the optical fluxes are in the range 15 < b < 17, partially overlapping those of the pg survey, but with a much better photometric accuracy (sigma_b ~ 0.1mag). our samples show that the true surface density of quasars in the range 15

Mission Description The Infrared Space Observatory (ISO) was the worlds first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths.
