The Plank Early Release Compact Source Catalogue was the first Planck product to be publicly released in Jan 2011. It was produced with a very rapid turnaround to facilitate follow-up observations with existing  c ryogenic observatories such as Herschel. It contained a list of all high reliability sources, both Galactic and extragalactic, that were derived from the first all sky coverage by Planck. i.e., using observations obtained from 12 August 2009 to 6 June 2010. Thus the full sky was covered once, and ~60% of the sky was covered twice. The goals were to achieve a photometric accuracy of 30% and a positional accuracy  1/5 of the beam FWHM in the RMS sense.

The Catalogue of Compact Sources[edit]

Product description[edit]

The 2013 Planck Catalogue of Compact Sources (PCCS), and the 2015 new version of the catalogue (PCCS2 and PCCS2E), are single-frequency lists of sources extracted from the Planck full mission maps. In the PCCS, the analaysis was done on the total intensity nominal mission maps. In the PCCS2/PCCS2E, the full mission maps in total intensity and polarization have been used.

The main difference between the PCCS2 and PCCS2E is that the sources in the PCCS2 have been validated, either statistically or with external catalogues, while the PCCS2E contains all the remaining sources where an estimate of their reliability has not been made. By definition, the reliability of the PCCS2 is > 80%, but a new flag has been added to the PCCS2 catalogues that allows one to select a subsample of sources with a higher level of reliability (e.g., 90%, 95%, etc.).

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 projected flat patches. For the other methods (Point Spread Function fitting, Gaussian fitting and Aperture photometry), the analysis is performed directly on the 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.

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


The analysis in polarization has been performed in a non-blind fashion, looking at the position of the sources previously detected in total 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 being 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).

Before using the PCCS and PCCS2, please read the Cautionary Notes in the PCCS Planck-2013-XXVIII[1] and PCCS2 [2] papers.

Production process[edit]

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

Inputs[edit]

The data obtained from the Planck nominal mission (August 12 2009 - November 27 2010) and the Planck full mission (August 12 2009 - August 3 2013) have been processed into full-sky maps by the HFI and LFI Data Processing Centres (DPCs). A description of the processing can be found in the LFI and HFI DPC papers [3][4].

The PCCS2 full mission data consist of five complete sky surveys for HFI and eigth complete sky surveys for LFI. This implies that the flux densities of sources obtained from the full mission maps are the average of at least 5 to 8 observations, in the LFI and HFI. The nine Planck frequency channel maps are used as input to the source detection pipelines. The relevant properties of the frequency maps and main parameters used to generate the catalogues are summarized in Tables 1 and 2 (2015 PCCS2/PCCS2E) and Table 3 (PCCS).

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

Notes 2015 PCCS2

  1. Source names consist of a prefix and a position. The prefix used is PCCS1 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 Planck map would be labelled PCCS1 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 channels: 100, 143, 217 and 353 GHz. All “PX” fields contain NULL each time a “Bright” detection is found and the “P” field contains a value different from “0”.
    - Polarisation 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. WHICH_ZONE this column encodes the zone or zones 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 targeted at 80%, this will be the lowest possible value in this column. Where possible this will be provided in steps of 1% otherwise it will be in steps of 5%. NOTE: this column is only present when the version keyword in the primary header is set to PCCS2.

Notes 2013 PCCS

  1. Source names consist of a prefix and a position. The prefix used is PCCS1 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 Planck map would be labelled PCCS1 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, or 2, based on the following conditions:
    = 2: The source has a clear counterpart in one of the catalogues considered as ancillary data.
    = 1: The source has no clear counterpart in one of the ancillary catalogues but it has been detected by the internal multi-frequency method (LFI channels) or match with neighbouring frequencies, above or below (HFI channels).
    = 0: The source has no clear counterpart in one of the ancillary catalogues and it has not been detected by the internal multi-frequency method or neighbouring frequencies.
  4. The x-axis is defined for each source as parallel to the line of constant colatitude, with the same direction as the longitude. Therefore the position angles are measured anticlockwise from the y-axis.


The SZ catalogues[edit]

The Planck SZ catalogue is constructed as described in SZ catalogue and in section 2 of Planck-2013-XXIX[5].

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[5].

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.

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.

The Galactic Cold Cores Catalogue[edit]

TBW - Montier


The Catalogue of high-z Sources[edit]

TBW - Montier


The ERCSC[edit]

The Plank Early Release Compact Source Catalogue was the first Planck product to be publicly released in Jan 2011. It was produced with a very rapid turnaround to facilitate follow-up observations with existing c ryogenic observatories such as Herschel. It contained a list of all high reliability sources, both Galactic and extragalactic, that were derived from the first all sky coverage by Planck. i.e., using observations obtained from 12 August 2009 to 6 June 2010. Thus the full sky was covered once, and ~60% of the sky was covered twice. The goals were to achieve a photometric accuracy of 30% and a positional accuracy 1/5 of the beam FWHM in the RMS sense.

The ERCSC consisted of nine source lists, one at each of the nine Planck frequency channels. The number of sources in the lists range from 705 at 30 GHz to 8988 at 857 GHz. No attempt was made to cross-match the sources from the different frequencies due to the wide range of spatial resolutions (33 arcmin at 30 GHz to 4.3 arcmin at 857 GHz) spanned by Planck. Furthermore, a list of Cold Cores of interstellar molecular clouds within the Galaxy and a list of galaxy clusters detected through the Sunyaev- Zel’dovich effect (SZ), were also provided. These consisted of candidate sources that were detected using multifrequency algorithms that use the distinct spectral signature of such sources. The Cold Cores catalogue contained 915 sources while the SZ cluster catalogue consisted of 189 sources

In order to generate the ERCSC, four source detection algorithms were run as part of the ERCSC pipeline. A Monte-Carlo algorithm based on the injection and extraction of artificial sources into the Planck maps was implemented to select reliable sources among all extracted candidates such that the cumulative reliability of the catalogue is >90%. Reliability is defined as the fraction of sources in the catalog which have measured flux densities which are within 30% of their true flux density. There is no requirement on completeness for the ERCSC. As a result of the Monte-Carlo assessment of reliability of sources from the different techniques, an implementation of the PowellSnakes source extraction technique was used at the five frequencies between 30 and 143 GHz while the SExtractor technique was used between 217 and 857 GHz. The 10σ photometric flux density limit of the catalogue at $|b| > 30$ deg is 0.49, 1.0, 0.67, 0.5, 0.33, 0.28, 0.25, 0.47 and 0.82 Jy at each of the nine frequencies between 30 and 857GHz. Sources which are up to a factor of ~2 fainter than this limit, and which are present in "clean" regions of the Galaxy where the sky background due to emission from the interstellar medium is low, are included in the ERCSC if they meet the high reliability criterion. The sensitivity of the ERCSC is shown in the figure below. The ERCSC sources have known associations to stars with dust shells, stellar cores, radio galaxies, blazars, infrared luminous galaxies and Galactic interstellar medium features. A significant fraction of unclassified sources are also present in the catalogs.

The multifrequency information from Planck allows some basic classification of the sources to be undertaken. In the Galactic plane, at frequencies below 100 GHz, the majority of the sources are dominated by synchrotron or free-free emission. At the higher frequencies, the sources are almost exclusively dominated by thermal dust emission. At high Galactic latitudes however, the synchrotron sources dominate the source counts to 217 GHz with dusty sources being the primary source population at 353 GHz and higher. Recent attempts to classify a subset of the Planck 857 GHz sources at high latitudes based on cross-correlations with sources in other catalogs such as WISE and SDSS, found that almost half of them are associated with stars and low-redshift galaxies while a significant fraction (44%) might be interstellar medium features [20].

Full details on the construction, contents and usage of the ERCSC, ECC and ESZ catalogues can be found in Planck-Early-VII[21], Planck-Early-VIII[22], Planck-Early-XXIII[23].


Flux density limits


The figure shows the ERCSC flux density limits, quanitfied as the faintest ERCSC source at |b|<10 deg (dashed black line) and at |b|>30 deg (solid black line), compared to those of other wide area surveys (Planck-Early-VII[21]). Also shown are spectra of known sources of foreground emission as red lines. The ERCSC sensitivity is worse in the Galactic plane due to the strong contribution of ISM emission, especially at submillimeter wavelengths. At face value, the WMAP and Planck flux density limits appear to be comparable at the lowest frequencies, but the Planck ERCSC is much more complete as discussed in Planck-Early-VII[21].
