Stars CygOB2-000644 and CygOB2-072104 are both occultation and compound variables and were considered as eclipsing binary candidates in the present study. They are also reported as eclipsing binaries in HSP11. Left: J, H, and K light curves for each star. The median magnitude and ptp amplitude are also written in the plot, and the colors reflect the date of the observation, as in Fig. 4. Middle: phased light curve for each band. J, H, and K bands are shown as blue, green, and red respectively. Right: J vs. J − H CMD for the same star. Colors also reflect the date of the observation, as in Fig. 4.
