SuperWASP light curve. We show the time-series photometry that led to the discovery of J0113+31, as part of the SuperWASP transiting planet survey, overplotted on the final model light curve from the EB modelling (Sect. 3.5) in the V-band, which is used as a proxy for the non-standard SuperWASP filter. The primary eclipse of the M dwarf blocking the light of the more massive star has a transit-like shape (shown in inset). The error bar to the bottom left represents the median uncertainty of the SuperWASP photometric points, which are excluded for clarity.
