Ratio between the ST rms and the LT rms for the three pairs of indices (from top to bottom). Filled circles correspond to the most variable stars (i.e. with a better S/N), the threshold is a global Ca rms higher than 0.1. The solid line is the y = x line. One outlier in the middle panel (at a LT ratio of ~1) is not shown here for clarity.
