Results of CNN classifications (ravedr6.dr6_cnn)
The table has 426574 rows, 30 columns.
Description
The table provides atmospheric parameters and abundances along with their uncertainties for 420165 stars in the RAVE survey as result of a Convolutional Neural Network application. CNN-based methods provide a powerful way to combine spectroscopic, photometric, and astrometric data, without applying any priors in the form of stellar evolutionary models.
