Comparison between best-fit (MAP) model of the four-facula configuration versus input SOAP configuration. Left panels: best-fit photometric light curve presented as blue line; SOAP synthetic light curve shown as orange line with its errors, obtained by adding in quadrature data errors and jitter. A black cross marks the time at which the model (middle) and input SOAP (right) facula configurations are shown. Stellar flux is colour-coded as in Fig. 1, with the exception of the facula flux that has been modified to 10³ in order to enhance the visibility.
