LMC distance modulus obtained using the relations of Table 3 for the F+1O cases plotted against the central wavelength of the considered photometric bands. To avoid labels and symbols overlapping, the I band result has been shifted by −0.1 μm⁻¹. The top panel shows the results for the PLZ relations, while the bottom panel shows those for the PWZ relations. Different colours indicate the results obtained for different parallax shift values: L21 correction (black squares), L21 + Riess et al. (2021) offset (green squares), L21 + Molinaro et al. (2023) (violet squares). Empty and grey-filled squares indicate the results obtained excluding and including the δ coefficient, respectively.
