Similar to Fig. 2 for anti-solar DR candidates beyond the solar metallicity range, summarized in Table 2. All of them are part of the optimistic sample. They are illustrated with green circles. Blue histograms on the x- and y-axes are proposed for the green dot sample. For comparison, we add dotted black histograms, which represent the whole set of candidates for all metallicities (i.e., the targets in Tables 1 and 2 ).
