Detailed description of the data product

This output data product contains the list of the membership associations of the galaxies in the detected clusters. This RICH-CL data product is similar to the detclMembers

output produced by the AMICO cluster detection code in PF DET-CL.

Keywords

This fits file is expected to contain the following keywords in the primary HDU, characterizing the important parameters of the product:

  1. DET_CODE: Name of the detection algorithm

  2. MODEL_ID: an identifier of the cluster model used in the filtering procedure

  3. SNR_THR: the S/N threshold for extracting a detection

  4. MAX_NB: the maximum number of structures to which a galaxy can be associated

  5. MIN_PROB: the minimum probability for the association to be saved in this catalog

Table

The richclMembers table is expected to contain the following columns, for each detected cluster:

  1. OBJECT_ID : galaxy identifier, as it appears in detclGalaxies (see detclin)

  2. ID_CLUSTER: identifier of the associated detected cluster, as it appears in detclClusters (see detclPZWAVClusters and ref:detclAMICOClusters)

  3. PMEM : probability (0 <= p <= 1) of the galaxy membership in cluster OBJECT_ID, according to “Pmem” method. Note that PMEM = PMEM_RAD * PMEM_Z

  4. PMEM_LERR : error associated with PMEM (lower/left side), according to “Pmem” method

  5. PMEM_UERR : error associated with PMEM (upper/right side), according to “Pmem” method

  6. PMEM_RAD : Cluster-centric (i.e. tangential for observer) component of PMEM

  7. PMEM_Z : redshift (i.e. along line of sight) component of PMEM

  8. PMEM_RS : probability (0 <= p <= 1) of the galaxy membership in cluster OBJECT_ID, according to “red sequence” method.

  9. PMEM_LERR_RS : error associated with PMEM, according to “red sequence” (lower/left side) method.

  10. PMEM_UERR_RS : error associated with PMEM, according to “red sequence” (upper/right side) method.
