Product description: Planck Catalogue of Compact Sources

A general description of the product, including e.g. figures related to the contents (e.g. maps, tables), and some explanation of its scientific meaning. If there are scientific warnings about the use of the product (User’s caveats), they should also be given here, or at least references to other explanatory documents (papers etc).

see pccs paper: 1. numb. sources / freq, 2. image with sky distribution 3. main parameters used

For full details, see paper...

Production process

Description of the Pipeline used to generate the product. In particular any limitations and approximations used in the data processing should be listed. Avoiding detailed descriptions of methods and referring to other parts of the ES and/or the relevant Planck papers for the details. References however should be quite detailed (i.e. it is not enough to direct the user to a paper, but the relevant section in the paper should be provided).

For a description of the production and validation processes of the Compact Source catalogue see the corresponding section.

Inputs

A list (and brief description to the extent possible) of the input data used to generate this product (down to file names), as well as any external ancillary data sets which were used.

• frequency maps
• RIMo
• effective beams

To be reviewed and compiled by Joaquin/Mark.

Related products

A description of other products that are related and share some commonalities with the product being described here. E.g. if the description is of a generic product (e.g. frequency maps), all the products falling into that type should be listed and referenced.

Meta Data

A detailed description of the data format of each file, including header keywords for fits files, extension names, column names, formats….

Note 1.- Source name designations consist of a prefix and a positional qualifier, the latter is in Galactic coordinates and specified as "Glll.ll±bb.bb" where the (l,b) values are truncated. The prefix used in the single band portion of the PCCS is PLCKddd PCCS catalogue at ddd GHz.

For example, a source detected at (l,b) = (120.237, 4.231) in the 545 GHz Planck map would be labelled PLCK545 G120.23±04.23.

Note 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.

Note 3.- The EXT_VAL flag has 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 NOT a clear counterpart in one of the catalogues considered as ancillary data but it has been detected by the internal multi-frequency method.
• 0 – The source has NOT a clear counterpart in one of the catalogues considered as ancillary data and it has NOT been detected by the internal multi-frequency method.

The PCCS source list in each frequency is structured as a FITS binary table having one row for each detected source.

The FITS primary header will have the following structure:

FITS primary header

FITS Keyword	Data Type	Units	Description
INSTRUME	String		LFI or HFI
VERSION	String		Version of PCCS
DATE	String		Date file created:yyyy-mm-dd
ORIGIN	String		Name of organization responsible for the data (LFI-DPC – HFI-DPC)

DATE-OBS	String	days	Start-up time of the survey: yyyy-mm-dd
DATE-END	String	days	Ending time of the survey: yyyy-mm-dd
