Planck Catalog of Compact Sources (PCCS)
About PCCS
The Planck Catalogue of Compact Sources (PCCS) is a sample of reliable
sources, both Galactic and extragalactic, extracted directly from the
Planck nominal maps. The first public version of the PCCS, a component of
Planck Data Release 1, is derived
from the data acquired by Planck between August 13 2009 and November 26 2010.
The PCCS consists of nine lists of sources, extracted independently from each
of Planck's nine frequency channels. The source lists contain 24 columns
per source at the LFI and HFI bands.
The 857 GHz source list
has six additional columns which give the flux densities and flux density
uncertainties at the three adjacent lower frequencies:
217, 353, and 545 GHz.
