Detailed description of the data product

This data product contains the list of the membership associations of the input catalogue galaxies in the input catalogue of detected clusters. This data product will be produced either by AMICO cluster detection code (see Galaxy Membership Output Product), or by the membership assignment code of PF RICH-CL (tbd).

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 (currently, AMICO is the only possible value)

  2. MODEL_ID: an identifier of the cluster model used in the detection 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 profclMembers table is expected to contain the following columns, for each detected cluster:

  1. ID_G : galaxy identifier, as it appears in detclGalaxies (see Galaxy catalogue Input Product)

  2. RA: Right Ascension of galaxy (degrees)

  3. DEC: Declination of galaxy (degrees)

  4. ID_C: identifier of the associated detected cluster, as it appears in detclClusters (see detclPZWAVClusters)

  5. P_C : probability (0 <= p <= 1) of the galaxy membership in cluster ID_C
