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:

DET_CODE: DETECTION PARAMETERS
MODEL_ID: Name that identifies the adopted model used in the filtering procedure
SNR_THR: the S/N threshold for extracting a detection
MAX_NB: SPECIFIC RICH PARAMETERS Maximum number of structures to which a galaxy can be associated
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:

Column name	Description	Unit
OBJECT_ID	Galaxy identifier, as it appears in detclGalaxies (see Galaxy catalog Input Product)	NA
ID_CLUSTER	Identifier of the associated cluster, as it appears out of DET-CL clusters catalog	NA
PMEM	probability (0 LE p LE 1) of the galaxy membership in cluster OBJECT_ID, according to Pmem method. Note that PMEM = PMEM_RAD * PMEM_Z	NA
PMEM_LERR	error associated with PMEM (lower/left side), according to Pmem method	NA
PMEM_UERR	error associated with PMEM (upper/right side), according to Pmem method	NA
PMEM_RAD	Cluster-centric (i.e. tangential for observer) component of PMEM	NA
PMEM_Z	Redshift (i.e. along line of sight) component of PMEM	NA
PMEM_RS	probability (0 LE p LE 1) of the galaxy membership in cluster OBJECT_ID, according to RedSequence method	NA
PMEM_LERR_RS	error associated with PMEM (lower/left side), according to RedSequence method	NA
PMEM_UERR_RS	error associated with PMEM (upper/right side), according to RedSequence method	NA
