Abstract:
    The Second Planck Catalogue of Compact Sources is a list of discrete
    objects detected in single-frequency maps from the full duration of
    the Planck mission and supersedes previous versions. It consists of
    compact sources, both Galactic and extragalactic, detected over the
    entire sky. Compact sources detected in the lower frequency channels
    are assigned to the PCCS2, while at higher frequencies they are
    assigned to one of two subcatalogues, the PCCS2 or PCCS2E, depending
    on their location on the sky. The first of these (PCCS2) covers most
    of the sky and allows the user to produce subsamples at higher
    reliabilities than the target 80% integral reliability of the
    catalogue. The second (PCCS2E) contains sources detected in sky
    regions where the diffuse emission makes it difficult to quantify the
    reliability of the detections. Both the PCCS2 and PCCS2E include
    polarization measurements, in the form of polarized flux densities, or
    upper limits, and orientation angles for all seven
    polarization-sensitive Planck channels. The improved data-processing
    of the full-mission maps and their reduced noise levels allow us to
    increase the number of objects in the catalogue, improving its
    completeness for the target 80% reliability as compared with the
    previous versions, the PCCS and the Early Release Compact Source
    Catalogue (ERCSC).

Description:
    The Low Frequency Instrument (LFI) DPC produced the 30, 44, and
    70GHz maps after the completion of eight full surveys (spanning the
    period 12 August 2009 to 3 August 2013). In addition, special LFI maps
    covering the period 1 April 2013 to 30 June 2013 were produced in
    order to compare the Planck flux-density scales with those of the Very
    Large Array and the Australia Telescope Compact Array, by performing
    simultaneous observations of a sample of sources over that period. The
    High Frequency Instrument (HFI) DPC produced the 100, 143, 217, 353,
    545, and 857GHz maps after five full surveys (2009 August 12 to
    2012 January 11).

Global notes:
Note (G1): Format is PCCS2 fff Glll.ll+bb.bb for sources in the PCCS2 and
  PCCS2E fff Glll.ll+bb.bb for sources in the PCCS2E, where fff is the frequency
  channel and (l, b) is the position of the source in Galactic coordinates
  truncated to two decimal places.
Note (G2): We follow the IAU/IEEE convention (Hamaker & Bregman 1996)
  for defining the angle of polarization of a source, and this convention is
  also used for the other angles in the catalogue. The angle is measured from
  the North Galactic Pole in a clockwise direction from -90 to 90 degrees.
Note (G3): Provided when the significance of the polarization measurement
  is > 99.99% and set to NULL otherwise.
Note (G4): The P_STAT flag gives the status of the marginal polarization
  detection, possible values are as follows:
   3 = Bright: P field filled in; all PX fields set to NULL.
   2 = Significant: P field is set to NULL; 0 is outside the PX 95% HPD;
        all PX fields are filled.
   1 = Marginal: P field is set to NULL; 0 is inside the PX 95% HPD, but mode of
        PX posterior distribution is not 0; all PX fields are filled.
   0 = No detection: P field is set to NULL; mode of PX posterior distribution
        is 0; PX_ERRL, ANGLE_PX, ANGLE_PX_ERR_LOWER, and ANGLE_PX_ERR_UPPER
        are set to NULL.
Note (G5): The EXTENDED flag has the value of 0 if the source is compact and the
  value of 1 is it extended. The source size is determined by the geometric
  mean of the Gaussian fit FWHMs, with the criterion for extension being
  sqrt(GAU_FWHMMAJ * GAU_FWHMIN) > 1.5 times the beam FWHM.
Note (G6): The EXT_VAL flag gives the status of the external validation,
  possible values are as follows:
   3 = The source has a clear counterpart in one of the catalogues used as
        ancillary data.
   2 = The source does not have a clear counterpart in one of the catalogues
        used as ancillary data but it has been detected by the internal
        multi-frequency method.
   1 = The source does not have a clear counterpart in one of the catalogues
        used as ancillary data and it has not been detected by the internal
        multi-frequency method, but it has been detected in a previous Planck
        source catalogue.
   0 = The source does not have a clear counterpart in one of the catalogues
        used as ancillary data and it has not been detected by the internal
        multi-frequency method.
Note (G7): The HIGHEST_RELIABILTY_CAT column contains the highest reliability
   catalogue to which the source belongs. As the full catalogue reliability is
   >= 80%, this is the lowest possible value in this column. Where possible this
   is provided in steps of 1% otherwise it is in steps of 5%.
Note (G8): The WHICH_ZONE column encodes the zone in which the source lies
   as follows:
   1 = source lies inside filament mask.
   2 = source lies inside Galactic zone.
   3 = sources lies in both filament mask and Galactic zone.
Note (G9) : This is provided only when P column is set to NULL; otherwise this
  column itself contains a NULL.
