Catalogue of Compact Sources[edit]

Product description[edit]

The second version of the Planck Catalogue of Compact Sources (PCCS2 and PCCS2E) is a set of single-frequency lists of sources extracted from the Planck full-mission maps in intensity and polarization.

The main difference between the PCCS2 and PCCS2E is that the sources in the PCCS2 have been validated, either statistically or by using external catalogues, while the PCCS2E contains the remaining sources for which it has not been possible to estimate their reliability. By definition, the reliability of the PCCS2 is > 80%, and a flag is available that allows the user to select a subsample of sources with a higher level of reliability (e.g., 90% or 95%).

Four different photometry methods have been used. For one of the methods, the native photometry from the Mexican hat wavelet detection algorithm, the analysis is performed on patches containing tangent plane projections of the map. For the other methods (aperture photometry, point spread function fitting, and Gaussian fitting), the analysis is performed directly on the full-sky maps.

The deeper completeness levels and, as a consequence, the higher number of sources compared with its predecessors the PCCS and the ERCSC, allows the extension of previous studies to more sources and to fainter flux densities.

PCCS2 in Intensity
Sky distribution of the PCCS2 intensity sources at three different channels: 30 GHz (red circles), 143 GHz (blue circles) and 857 GHz (green circles). The dimension of the circles is related to the brightness of the sources and the beam size of each channel.
PCCS2E in Intensity
Sky distribution of the PCCS2E intensity sources at three different channels: 30 GHz (red circles), 143 GHz (blue circles) and 857 GHz (green circles).

The analysis in polarization has been performed in a non-blind fashion, looking at the position of the sources previously detected in intensity. As a result, polarization flux densities and polarization angles have been measured for hundreds of sources with a significance >99.99%. This high threshold in significance has been chosen to minimize the possibility of misinterpreting a peak of the polarized background as a source. This implies that, in general, most of the polarized sources are very bright, introducing an additional selection effect.

PCCS2 in Polarization
Sky distribution of the PCCS2 polarization sources at three different channels: 30GHz (red circles), 44GHz (green circles) and 70GHz (blue circles).
Sky distribution of the PCCS2 polarization sources at three different channels: 100GHz (red circles), 143GHz (blue circles) and 217GHz (green circles) and 353 GHz (black).
PCCS2E in Polarization
Sky distribution of the PCCS2E polarization sources at three different channels: 30GHz (red circles), 44GHz (green circles) and 70GHz (blue circles).
Sky distribution of the PCCS2E polarization sources at three different channels: 100GHz (red circles), 143GHz (blue circles) and 217GHz (green circles) and 353 GHz (black).

Production process[edit]

For a description of the production and validation process of the PCCS2 see the corresponding section.

Inputs[edit]

The nine Planck frequency channel maps are used as input to the source detection pipelines. They contain 48 months of data for LFI channels and 29 months of data for HFI channels. This implies that the flux densities of sources obtained from the full-mission maps are the average of at least 8 observations for LFI channels or at least 5 observations for HFI channels. The relevant properties of the frequency maps and main parameters used to generate the catalogues are summarized in Tables 1 and 2.

The input data used to generate this product are the following:

Notes

  1. Source names consist of a prefix and a position. The prefix used is PCCS2 fff for the catalogue at fff GHz. The position is in Galactic coordinates and specified as "Glll.ll±bb.bb" where the (l,b) values are truncated to two decimal places. For example, a source detected at (l,b) = (120.237, 4.231) in the 545 GHz map would be labelled PCCS2 545 G120.23+04.23.
  2. 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 criteria for extension being sqrt(GAU_FWHMMAJ * GAU_FWHMIN) > 1.5 times the beam FWHM.
  3. The EXT_VAL flag takes the value of 0, 1, 2, or 3 based on the following conditions:
    3 – The source has a clear counterpart in one of the catalogues considered as ancillary data.
    2 – The source does NOT have a clear counterpart in one of the catalogues considered 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 considered 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 considered as ancillary data and it has NOT been detected by the internal multi-frequency method.
  4. Provided when the significance of the polarization measurement is > 99.99% and set to NULL otherwise.
  5. We follow the IAU/IEEE convention (Hamaker & Bregman 1996) for defining the angle of polarization of a source. The polarization angle is measured from the North Galactic Pole in a clockwise direction from -90 to 90 degrees.
  6. The PX fields are only available for the 100-353 GHz channels. All PX fields contain NULL each time a bright detection is found and the P field contains a value different from 0.
    Polarization detection status (P_STAT):
    3 – Bright. P field filled in; All PX fields set to NULL.
    2 – Significant. P field set to NULL; 0 is outside of the PX 95% HPD; All PX fields are filled.
    1 – Marginal. P field set to NULL; 0 is inside of the PX 95% HPD, but mode of PX posterior distribution is different from 0; All PX fields are filled.
    0 – No detection. P field set to NULL; mode of PX posterior distribution is 0; PX_ERRL, ANGLE_PX, ANGLE_PX_ERR_LOWER, ANGLE_PX_ERR_UPPER set to NULL.
  7. The WHICH_ZONE column encodes the zone in which the source lies. (1 – source lies inside filament mask, 2 – source lies inside galactic zone, 3 – sources lies in both filament mask and galactic zone). NOTE: this column is only present when the version keyword in the primary header is set to PCCS2_E.
  8. 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: this column is only present when the version keyword in the primary header is set to PCCS2.

Zone Map[edit]

For each frequency channel there is an associated map which defines the quantified-reliability and unquantified-reliability zones are on the sky.

The files are called:

S/N threshold map[edit]

For each HFI frequency channel there is an associated map which contains the S/N threshold used to accept sources into the PCCS2 and PCCS2E catalogues.

The files are called:

Noise map[edit]

For each HFI frequency channel there is an associated map which contains the detection noise as a function of position on the sky.

The files are called:

The structure of the files is as follows:

Noise map FITS file structure
Extension 0: Primary header, no data

The FITS extension contains a single precision HEALPix map of the detection noise at each location on the sky.

SZ Catalogue[edit]

The Planck SZ catalogue is constructed as described in SZ catalogue and in section 2 of Planck-2013-XXIX[2].

Three pipelines are used to detect SZ clusters: two independent implementations of the Matched Multi-Filter (MMF1 and MMF3), and PowellSnakes (PwS). The main catalogue is constructed as the union of the catalogues from the three detection methods. The individual catalogues are provided for the expert user in order to assess the consistency of the pipelines. The completeness and reliability of the catalogues have been assessed through internal and external validation as described in sections 3-6 of Planck-2013-XXIX[2].

The union catalogue contains the coordinates and the signal-to-noise ratio of the detections and a summary of the external validation information, including external identification of a cluster and its redshift if it is available.

The individual catalogues contain the coordinates and the signal-to-noise ratio of the detections, and information on the size and flux of the detections. The entries are cross-referenced to the detections in the union catalogue.

The size of a detection is given in terms of the scale size, $\theta_\mathrm{s}$, and the flux is given in terms of the total integrated Comptonization parameter, $Y = Y_{5r_{500}}$. The parameters of the GNFW profile assumed by the detection pipelines is written in the headers in the catalogues. For the sake of convenience, the conversion factor from $Y$ to $Y_{500}$ is also written in the header.

The full information on the degeneracy between $\theta_\mathrm{s}$ and $Y$ is included in the individual catalogues in the form of the two-dimensional probability distribution for each detection. It is computed on a well-sampled grid to produce a two-dimensional image for each detection. The degeneracy information is provided in this form so it can be combined with a model or external data to produce tighter constraints on the parameters.

The union catalogue is contained in COM_PCCS_SZ-union_R1.12.fits.

Notes

  1. Format PSZ1 Glll.ll±bb.bb where (l, b) are the Galactic coordinates truncated to 2 decimal places.
  2. For PwS, this is the S/N evaluated in a manner compatible with the MMF pipelines. For MMF1 and MMF3, it is identical to SNR.
  3. Ext. 2 contains a three-dimensional image with the two-dimensional probability distribution in $\theta_\mathrm{s}$ and $Y$ for each detection. The probability distributions are evaluated on a 256 × 256 linear grid between the limits specified in Ext. 1. The limits are determined independently for each detection. The dimension of the 3D image is 256 × 256 × n, where n is the number of detections. The first dimension is $\theta_\mathrm{s}$ and the second dimension is $Y$.

Notes

  1. Unabsorbed X-ray flux measured in an aperture of 5 arcmin in the band [0.1-2.4] keV. The aperture is centered on the Planck position, except for candidates associated with a BSC source for which we adopt the X-ray position. For sources with [math](S/N)_{RASS} \lt 1\sigma[/math], we only quote an upper limit.
  2. SZ signal re-extracted fixing the size to the X-ray size provided in the MCXC catalogue at the X-ray position, for PSZ clusters identified with MCXC clusters.
  3. Computed in the Planck data at the X-ray position fixing the size to the X-ray size provided in the MCXC catalogue, for PSZ clusters identified with MCXC clusters.
  4. Source for redshifts:
    -1 : No redshift available

Caveats[edit]

The following issue was found in Feb. 2014 in R1.11 of the MMF3 catalogue: the POS_ERR field values are overestimated by a factor 3.125 on average. This issue has been resolved in R1.12. A corrected version of the union catalogue has also been produced (also R1.12)

The approximate 68% (1-sigma) confidence interval in the POS_ERR field is computed as half of the 95% (2-sigma) confidence interval. Previously this was erroneously described as a 95% confidence interval.
