Variation in indicators as a function of RV for the full data set (left panels) and the smaller subsample comprising map 9 (right panels). Colour indicates rotational phase. Closed circles are from map 6, and open circles are from map 7. Data points with successive rotational phases, from phases 0 to 1.0, are connected with the light grey solid line. The corresponding surface brightness image for the map 9 (combined maps 6 and 7) is shown in Fig. 6. For the NIR data, points with error bars that are greater than the mean error shown are indicated by an asterisk. A representative error bar is shown in black.
