PL relations obtained for several bands. In order, from top to bottom and left to right, we show the Gaia G_BP, G, and G_RP bands; Johnson-Cousins I, J, H, and K bands; VISTA J, Y, and K_s bands; and the Rubin-LSST g, r, i, z, and y bands. Different colours reflect the three different metallicities. The dashed lines correspond to the relations from RRL models (Marconi et al. 2015, 2022), while the relations from Sicignano et al. (2024) for the Gaia and VISTA bands are plotted in green and yellow.
