Scientific paper

ESA's Planck satellite, in addition to improving anisotropy measurements of the CMB, is performing an all-sky, low resolution, survey in nine bands from 30 to 857 GHz every 6 months, and extragalactic source detections are on-going. We propose to complete the observation of a sample of selected objects simultaneously with the Planck satellite in three pairs of 2-GHz-wide channels from 4.5 to 44 GHz also for two satellite complete sky surveys. These observations are providing information useful for reconstructing the SED across the radio and FIR bands in several epochs to investigate the properties of populations, and improving the models that describe the physics of sources, and values of flux density and polarization useful for Planck calibration, and to quantify the quality of the source detection techniques applied to the Planck maps. The satellite began collecting data in mid August 2009. We ask for at least 4 hours a week to complete the observations of a sample of 335 objects, during, at least, two complete sky surveys of the satellite, i.e. up to the end of August.
