Left panel: same as in the left panel of Fig. 1 but showing only the 57 RR Lyrae stars in the Gold sample plotted as black filled circles and using violet filled circles for V43, V60 and V63. We computed revised mean magnitudes for these three stars (see text for details). Right panel: G vs G_BP – G_RP CMD of UMi’s spectroscopically confirmed members and the 57 RR Lyrae stars in the Gold sample. Symbols are as in the left panel. The black crosses mark the V43, V60 and V63 positions on the CMD using the unrevised magnitudes.
