GMM Catalogue

Catalogue with probabilistic classification of galaxies based on their ionization source using Gaussian Mixture Models

This catalogue was designed to provide soft/probabilistic classifications for galaxies based on their ionization source. The data consists of a combination of the BPT and WHAN diagrams.

The probabilistic classification of galaxies via GMM is constructed using data from the SDSS DR7 and the SEAGal/STARLIGHT catalogues is available at Catalogue.
