Two-component LLE projection of gas density, mass, and CH3OH, CH3CN, CH3CCH rotational temperature and column density for 32 YSOs for which the rotational diagram yielded this information. The colours correspond to the labels assigned by a three-component, BIC-optimized GMM clustering. The ellipses encompass 95.4% (2σ) of the probability mass of each GMM cluster.
