Empirical cumulative distribution functions for a) temperatures, b) line FWHMs, c) source diameter, and d) molecular column density. The different tracers and components are drawn with different colours, as indicated in the legend in the lower right corner of panel b). “CO” refers to properties obtained from C¹⁷O and C¹⁸O transitions from Giannetti et al. (2014), and NH₃ properties are taken from Wienen et al. (2012). Dust properties from König et al. (2017) are included only in panels a) and c).
