K2 light curve of EPIC 211759736 spanning 75 days. Top panel: black curve is the raw light curve, while the thin red curve is a spline-smoothed version. Bottom panel: difference between the black and red curves in the top panel, showing more clearly both the primary and secondary eclipses. We highlight the difference in vertical scale by a factor of ∼15. The eclipse depths are at most 5% of the full amplitude (≈0.2 mag) of the light variations.
