Random forest classification probabilities plotted as a function of the PSF r magnitude for the 111 million newly classified sources. A histogram of the PSF r magnitude is also overlaid normalised for each class. 13%, 15% and 70% of the galaxies, quasars, and stars have classification probabilities greater than 0.99. 70%, 34% and 93% of galaxies, quasars, and stars have classification possibilities greater than 0.9 (as detailed in Fig. 17).
