Notes. Longitudes are with respect to HJD 2457510.5105 (BRITE-Toronto), HJD 2453680.6598 (WIRE), HJD 2454115.2887 (SMEI), and HJD 2458625.8020 (TESS). Spots are ordered according to their impact on the light curve. Modal values are provided together with mean values and 90% credibility limits. The set of mean parameter values may differ markedly from the set of modal values due to the skewness of the posterior. The residuals in mmag of the photometric data to the model light curve are rms values.
