Chromatic analysis. Red points in the top subpanels show measurements from the sampling step in Fig. C.2, for the amplitude (top panels) and frequency (bottom panels) of the first (blue box) and second (orange box) wiggle components. Bottom subpanels show residuals between the measurements and their best-fit model (solid black curves). Blue points are outliers automatically excluded from the fit through sigma-clipping. The wave-like variations in the measurements are an artifact of the sampling method.
