BP/RP spectrum prototypes (Xp Spectra) from Self-Organised-Map of OA module. (gaiadr3.oa_neuron_xp_spectra)
The table has 78300 rows, 7 columns.
Description
This is the table hosting the prototype BP/RP spectrum corresponding to each of the neurons of the Self-Organised-Map produced by the Apsis module OA. Other neuron attributes, such as statistics on various parameters, are available in another table: OaNeuronInformation. See Section cu8par_apsis_oa for further details.
