Top panel: OM light curve of HDE 228766 in the UVW2 filter. Second and third panels from top: NSVS light curve of HDE 228766. Open squares stand for data from Obj. ID 5725284, while filled circles indicate Obj. ID 8495712 in the NSVS database (Woźniak et al. 2004). In the second panel, all 117 data points are shown, including those which were obtained via a deblending procedure. The third panel shows only those 42 data points that remain after rejecting the measurements obtained via PSF deblending. Bottom panel: SuperWASP light curve of HDE 228766.
