Light curves of WASP-11/HAT-P-10 b transits compared with the best jktebop fits. The dates, the telescopes, and the filters used for each transit event are indicated. Residuals from the fits are displayed in the right panel. Starting from the top, the first three light curves are from this work, whereas the last two are from Bakos et al. (2009). The second and third light curves are related to the same transit event.
