Fourier parameters R21 (upper left), ϕ21 (bottom left), R31 (upper right), and ϕ31 (bottom right) as a function of the logarithm of the period, as obtained in this study for the ɡriz bands, along with those reported by OCVS in the I band for RRab (circles) and RRc (crosses) stars. Our ɡriz data and OGLE’s I-band data are represented using the same color scheme as in Figure 2.
