Self-Organized Map neurons information of Apsis Outliers (OA) (gaiadr3.oa_neuron_information)

The table has 900 rows, 78 columns.

Description

This is the table hosting the content of a Self-Organized Map calculated from a dataset composed by outliers by the Apsis module OA. Each entry corresponds to parameters estimated for one particular neuron of the map. The prototype BP/RP spectrum for a particular neuron is available in another table: OaNeuronXpSpectra. See Section cu8par_apsis_oa for further details.
