Detailed Description of the Data Product
_________________________________________
.. DetailedDescStart

Data Product "Associations" from PF DET-CL AMICO.
This data product contains the list of the membership associations of the (input catalogue) galaxies in the (output) detected clusters. This data product will only be produced by AMICO detection code.

Keywords
+++++++++++++

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

#. **DET_CODE**: Name of the cluster detection algorithm (currently, AMICO is the only possible value)
#. **MODEL_ID**: an identifier of the cluster model used in the filtering procedure of the detectin
#. **SNR_THR**: the S/N threshold for extracting a cluster detection
#. **MAX_NB**: the maximum number of structures to which a galaxy can be associated
#. **MIN_PROB**: the minimum probability for the association to be saved in this catalog
#. **MEMB_CODE**: Name of the membership assignment code (here "AMICO". May also be "PMEM" or "RS" if issued from RICH-CL)


Table
+++++++++++++

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

#. **OBJECT_ID** : Galaxy identifier, as it appears in detclGalaxies (see :ref:`detclin`)
#. **ID_CLUSTER**: identifier of the associated detected cluster, as it appears out of :ref:`detclAMICOClusters`.
#. **P_CLUSTER** : probability (0 <= p <= 1) of the galaxy membership in cluster ID_CLUSTER
