Examples of folded light curves in J (blue), H (green), and K_s (yellow). The solid and dashed lines represent the mean magnitudes considering a straight average over the available observations and best-fit template model (if available), respectively. The color bands around data points correspond to a 2σ range around the mean. The VVV-ID and periods are included on top of each panel. In the bottom right panel, no data are available in the J and H bands, and so only the K_s photometry shown. We note that distances could be computed for both stars in the upper row, but not for those in the bottom row, due to saturation (bottom left panel) or a period that places the star outside the distance indicator regime (bottom right panel).
