Top: V band light curves for J093010A (data from Koo et al. 2014) expressed in PHOEBE flux units, with best-fitting PHOEBE model curves overplotted (dashed red lines indicate model with no spot, solid blue lines indicate one-spot example model). Middle: residuals from no-spot model, showing out-of-eclipse semi-sinusoidal light variation unaccounted for. Bottom: residuals from one-spot model, largely correcting for these variations.
