The VizieR Kohonen map

This Kohonen Self-Organizing Map is based on a neural network analysis of the keywords associated to the catalogues (see Poincot et al., 1998A&AS..130..183P; and Lesteven et al., 1996VA.....40..395L)

Each dot marks a map area; colour denotes the density or the clustering tendency of the documents; deep blue areas have the lowest density. Just click any area on the map to get the corresponding list of catalogues found in that area.
