enough to not affect the statistical results of the whole cluster sample. Within the ATLASGAL Galactic range, a much more thorough revision was done (see Section \[sec:huge-table\]), further refining the cross-identifications, and even recognizing a few duplications and spurious clusters which were excluded from the final sample (see Section \[sec:spurious\]).
