Upper panel: Kepler LHS 6343 transit photometry from Q0–Q6 (black dots) and the best fit model obtained as described in Sect. 3.1 (red line); crosses indicate data corresponding to spot occultations during the transits. They are not used for modelling the transit. Lower panel: the residuals of the transit best fit (black dots) and the points corresponding to spot occultations (crosses) vs. the time elapsed from mid-transit.
