Light curves for the GLOESS fits to four Cepheids (CEP001, CEP002, CEP003, CEP004), as in Figure 2. The average magnitude and its error are calculated using the GLOESS fits, shown in this plot as the continuous lines. In cases where the data were not well sampled, J, H, or K_s magnitudes are not plotted and were calculated by finding the average value of the data points (see Table 2). The FourStar data, plotted as stars, agree with those of F12, as discussed in Section 2.4. The J, H, and K_s fits are dominated by the F12 data.
