Representative phase-binned light curves of FU and FO Cepheids with varying periods at all wavelengths (grizJHK_s). The magnitudes in g, r, J, H bands were offset by −0.5, −0.2, −0.1, +0.1 for visualization purposes. The best-fitting Fourier series fits are also shown as dashed lines. The Gaia Source ID, pulsation mode, and period are listed at the top of each panel. The light curve quality flag is given at the bottom left of each panel. The uncertainties in magnitudes at a given phase point also include the scatter at that phase in the original light curves.
