Comparison of the Wesenheit magnitudes of UMi Gold sample RR Lyrae stars and the ${\text{PW}}_{G,G_{BP},G_{RP}}\text{Z}$ relation of Garofalo et al. (2022) (solid line) ±3σ (dashed lines), fixed to the distance modulus, 19.23 ± 0.11 mag that we derived using the M_G − [Fe/H] relation. The violet filled circles mark the RR Lyrae stars V43, V60 and V63 plotted with revised mean magnitudes after our analysis of their light curves (see text for details).
