Same as Fig. 3 for the calibrated abundances. Logarithm of the p-values of the K–S two-sample test for each pair of clusters. The elements of the main diagonal and above the main diagonal represent the lowest p-value found among all the elements, while the elements below the main diagonal represent the p-value for carbon. The cells are colored in shades of red as shown in the color bar. Red colors are saturated at 0.01. Superscripts in the cluster names indicate the number of stars in the cluster. At the center of each cell, we show the element for which the p-value is calculated. Two blue lines separate the objects into globular and open clusters.
