Processing function using the data product¶
CAT-CL
LE3-PF-CL
Proposed for inclusion in EAS/SAS¶
This product is proposed for inclusion in the SAS: Yes
CAT-CL output catalogues should be used directly by the SWG-CL for the cosmological analysis. These catalogues are both inputs for downstream CL PFs, but also final products on their own accord.

Detailed Description of the Data Product¶
This output product contains the merged catalog of candidate clusters This data product gathers a number of quantities (and their associated errors) characterizing the detected clusters, issued from PFs DET-CL, Z-CL, PROF-CL, SIG-CL, RICH-CL, LMF-CL and/or COMB-CL.
NOTE: The selection of columns indicated below is not definitive and requires a discussion. Does is aim at being complete (i.e. gather all columns from the input PFs) or rather a selection of the most representative quantities (in this case, quantities TBC) ? For the moment, only the columns issued from the PFs expected to participate in SC8 appear explicitely
The lines are the union of the two cluster catalogs, issued from each of the cluster detection codes (AMICO and PZWAV). Therefore, order to track individual and cross-identified detections, the following additional columns are used : - A unique identifier of this union catalog of the candidate clusters - Specific flags identifying, for a given cluster, which detection code was used - A reference for cross-identified (i.e. cross-matched) clusters.

Table¶
NOTE: In a purpose of clarity, the quantities included in the CAT-CL output table are hereafter presented in distinct tables, each corresponding to a different PF origin (or specific to CAT-CL). These tables will be merged as a single one in the actual CAT-CL output.
