Distribution of the 4 136 544 sources in the 2 D latent output space of our ANN designed to perform an unsupervised clustering of variable sources (see Section 4 and Fig. 5 for more details). Different overdensities of points correspond to different (sub)types of variability. A first identification of the overdensities can be found in Fig. 14. For future reference we also depict the parts of this latent space shown in Figs. 15–20 with rectangles and provide the figure number is in one of the corners.
