Notes. To be read from left to right, e.g. ~39% of the “highcolumn density” region overlaps with the “low temperature” region. Conversely, ~ 9% of the “low temperature” region overlaps with the “high column density” region. The majority of these overlaps are discussed in this paper as they correspond to regions themselves (e.g. the overlap between the “high column density” and “low temperature” regions is identical to the region “high column density, low temperature”). The exceptions to this are the three regions that are not based on column density or temperature thresholds, namely “H II”, “radical region”, and “dense PDR”.
