Scientific paper

ESA's Planck satellite will perform an all-sky, but low resolution, survey in nine bands from 30 to 857 GHz, and is expected to detect a large sample of extragalactic radio sources down to a few tenths of a Jy. We propose the observation of a sample of selected objects simultaneously with the Planck satellite in three pairs of 2-GHz-wide frequency channels from 4.5 to 45 GHz and in a channel at 1.4 GHz. These observations will provide information useful for reconstructing the SED across the radio and FIR bands in several epochs to investigate the properties of populations, and will provide values of flux density and polarization useful for calibrating Planck, and quantifying the quality of the point source detection techniques applied to the Planck maps. The satellite will be launched in April 2009 and will begin collecting data in early July. We ask for 4 hours a week, to observe almost simultaneously a sample of about 300 objects, during, at least, two complete sky surveys of the satellite, i.e. 12 months. For this reason we ask that continuing status be allocated to this project.
