Detailed Description of the Data Product

This output product contains the galaxy membership estimates of the candidate clusters, from RICH-CL

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: DETECTION PARAMETERS

  2. MODEL_ID: Name that identifies the adopted model used in the filtering procedure

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

  4. MAX_NB: SPECIFIC RICH PARAMETERS Maximum number of structures to which a galaxy can be associated

  5. MIN_PROB: Minimum probability for the association to be saved

Table

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

Catalog: 14 columns table
