Introduction
============

The OU-LE3 CAT-CL PF shall provide

The input products are:
 - The inputs of DET-CL: the Galaxies catalogue, the photometric redshift catalogue (not mentioned on the figure above), the photometric mask, and
 - The outputs of DET-CL: the catalogue of cluster candidates, and the galaxies membership catalogue
 - The "truth tables": the mock catalogue of galaxies (with their photometic and possibly spectroscopic redshifts, and halo/cluster membership), and the mock catalogue of haloes/clusters
 - The outputs of RICH-CL: the clusters' richness and galaxies memberships
 - Optionally: the output of "cluster characterisation" PFs (more details below)

The output products are:

- An output catalog of clusters including, for any cluster detected by any of the two cluster-finding algorithm, all the relevant quantities and associated uncertainties from "cluster characterisation" PFs:

  * from DET-CL: central position in projected coordinates (right ascension and declination), signal-to-noise of the detection, richness or/and amplitude, detection redshift, detection size;
  * from RICH-CL: refined richness estimates (several estimates at different angular sizes);
  * from Z-CL: refined redshifts (photometric and, if available, spectroscopic and a combination of the two);
  * from COMB-CL: weak lensing mass estimates (several estimates at the same angular sizes used to estimate the richness)

And, in the future:

  * from SIG-CL: velocity dispersion;
  * from PROF-CL: refined size estimate, refined center estimate ;
  * from LMF-CL: integrated luminosities and stellar masses (several estimates at the same angular sizes used to estimate the richness);

  *NOTE: During the SC8, only the quantities from PFs actually taking part in the SC8 are included. Quantities from other PFs will be added later on*

  In addition to these quantities, specific identifiers allow to track the origin of each cluster candidate and its possible cross-match with another cluster candidate found using a different method.

- A output catalogue of galaxies containing the references to all galaxies possibly associated with some cluster candidate
