Core parameters with a Spearman correlation coefficient of |r_S|≥ 0.4. The results for the cores in ISOSS J22478+6357 and ISOSS J23053+5953 are shown in green (this work, Tables 4–6) and the results for the cores of the original CORE sample are presented in blue (Gieser et al. 2021). In each panel, the correlation coefficient r_S and p-value are shown in the top left corner. For completeness, the clump-average M/L ratio taken from Ragan et al. (2012) of the corresponding ISOSS cores (Table 4) is shown in red.
