Activation map of the Main Experiment. A pie chart representing the distribution of labels has been overlaid on each cell of the map. For each cell, it has been indicated: the number of galaxies (GAL), the number of stars (STAR), and the number of AGNs, from the LS; the number of unlabeled objects (Δ); the total number of labeled and unlabeled objects (TOT). The background color intensity reflects the number of objects falling in the cell.
