Comparison of the clump parameters of the regions. The temperature, T_dust, luminosity, L, mass, M, and distance, d, are listed in Table 1 and are taken from the ATLASGAL survey (Schuller et al. 2009; Urquhart et al. 2018). The region peak intensity, and flux density, of the ALMA 3 mm continuum data are listed in Table 2. The colors of the data points highlight the four evolutionary stages: IRDC (red), HMPO (green), HMC (blue), and UCHII region (purple). The Spearman correlation coefficient (r_S) and the p-value, with a(b) meaning a × 10^b, are shown in the bottom-right corner.
