Pearson correlation (lower triangle) and Spearman correlation (upper triangle) matrices for all hot cores. Pearson correlation coefficients are used to quantify linear relationships, while Spearman rank correlation coefficients are adopted to assess monotonic trends that may be nonlinear. The bold marks the parameter pairs whose absolute correlation coefficients are above 0.5, for which linear fitting parameters are listed in Table D1.
