In Table \[tab:catalogs\], for a given reference, we represent as $N_{\rm cl}$ the absolute (original) number of clusters in the catalog, whereas $N_{\rm cl}^*$ is the number of different entries with respect to all catalogs listed before it (i.e., after merging). The optical catalogs were put first, so that any cluster visible in the optical is considered an *optical* cluster. The infrared lists (including the *NIR* and *MIR* clusters) were positioned afterwards in chronological order, and therefore following roughly the discovery time. Absolute and after-merging numbers are presented for the total sky range of every list, the ATLASGAL Galactic range ($|\ell| \le 60\degr$ and $|b| \le 1.5\degr$), and finally for only those associated with ATLASGAL emission according to the criterion explained in Section \[sec:evolutionary-sequence\]. We warn that the number of clusters
