Correlations between the main parameter pairs in the three overlapping catalogs. The strength of the correlations between each pair is color-coded: light blue cells represent no significant correlations (< 0.8σ); dark blue cells represent weak correlations (0.8σ − 1.5σ). Black cells are not relevant due to the absence of reported uncertainties of v_micro or because they link the same quantities (e.g., ΔT_eff with ΔT_eff). The estimated strength of the correlations is based on the comparison of the correlation slopes with the average of the reported individual uncertainties of stellar parameters and RVs. The stars have been separated into dwarfs (left column) and giants (right column).
