Planck 2013 results. XXVIII. 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 (it is 90% complete at 180 mJy in
the best channel) and better angular resolution (from ~33' to ~5') than
previous all-sky surveys in this frequency band. By construction its
reliability is >80% and more than 65% of the sources have been detected at
least in two contiguous Planck channels. In this paper we present the
construction and validation of the PCCS, its contents and its statistical
characterization.
