The Planck Multi-frequency Catalogue of Non-thermal (i.e. synchrotron-dominated) Sources (PCNT) observed
between 30 and 857 GHz by the ESA Planck mission. This catalogue was constructed by selecting objects
detected in the full mission all-sky temperature maps at 30 and 143 GHz, with a signal-to-noise ratio (S/N)>
3 in at least one of the two channels after filtering with a particular Mexican hat wavelet. As a result, 29
400 source candidates were selected. Then, a multi-frequency analysis was performed using the Matrix Filters
methodology at the position of these objects, and flux densities and errors were calculated for all of them
in the nine Planck channels. This catalogue was built using a different methodology than the one adopted for
the Planck Catalogue of Compact Sources (PCCS) and the Second Planck Catalogue of Compact Sources (PCCS2),
although the initial detection was done with the same pipeline that was used to produce them. The present
catalogue is the first unbiased, full-sky catalogue of synchrotron-dominated sources published at millimetre
and submillimetre wavelengths and constitutes a powerful database for statistical studies of non-thermal
extragalactic sources, whose emission is dominated by the central active galactic nucleus. Together with the
full multi-frequency catalogue, we also define the Bright Planck Multi-frequency Catalogue of Non-thermal
Sources (PCNTb), where only those objects with a S/N > 4 at both 30 and 143 GHz were selected. In this
catalogue 1146 compact sources are detected outside the adopted Planck GAL070 mask; thus, these sources
constitute a highly reliable sample of extragalactic radio sources. We also flag the high-significance
subsample (PCNThs), a subset of 151 sources that are detected with S/N > 4 in all nine Planck channels, 75
of which are found outside the Planck mask adopted here. The remaining 76 sources inside the Galactic mask
are very likely Galactic object...s. More information: https://wiki.cosmos.esa.int/planck-legacy-archive/index.php/Catalogues

Mission Description
Planck is ESA's mission to observe the first light in the Universe. Planck was selected in 1995 as the third
Medium-Sized Mission (M3) of ESA's Horizon 2000 Scientific Programme, and later became part of its Cosmic
Vision Programme. It was designed to image the temperature and polarization anisotropies of the Cosmic
Background Radiation Field over the whole sky, with unprecedented sensitivity and angular resolution. Planck
is testing theories of the early universe and the origin of cosmic structure and providing a major source of
information relevant to many cosmological and astrophysical issues.
