The Planck Catalogue of Compact Sources
  The Planck Catalogue of Compact Sources (PCCS) is the catalogue of sources
detected in the first 15 months of Planck operations, the nominal mission. It
consists of nine single-frequency catalogues of compact sources, both Galactic
and extragalactic, detected over the entire sky. The PCCS covers the frequency
range 30 -- 857 GHz with higher sensitivity and better angular resolution than
previous all-sky surveys in the microwave band. It is 90 percent complete at
180 mJy in the best channel, and the resolution ranges from 32.88 to 4.33 arc
minutes. By construction its reliability is greater than 80 percent, and more
than 65 percent of the sources have been detected at least in two contiguous
Planck channels. Many of the Planck PCCS sources can be associated with stars
with dust shells, stellar cores, radio galaxies, blazars, infrared luminous
galaxies and Galactic interstellar medium features. Here we summarize the
construction and validation of the PCCS, its contents and its statistical
characterization.
