Strength of correlations in the APOGEE−GALAH parameter and abundance pairs. The color-coding is as follows: Black cells are indeterminable, light blue cells represent no significant correlation (< 0.8σ), dark blue cells indicate a weak correlation (0.8σ − 1.5σ), and the magenta cells mean strong correlation (> 1.5σ). Our estimations are based on the average correlation of reported individual uncertainties of stellar parameters and abundances. Dwarf (left panel) and giant stars (right panel) are separated.
