Declination of the 50 targets presenting the largest RSM′ values as a function of their respective score. The ten most favourable targets are annotated with their names. The areas of the data points scale with the planetary radii. For reference, an exemplary data point corresponding to 1 R_Jup is shown in the bottom right. The colour of a given data point indicates the respective planetary equilibrium temperature. Since non-transiting planets do not have any measured equilibrium temperatures listed in the NASA exoplanet archive (Akeson et al. 2013), they are shown as empty data points. Planets that had previously been targeted for reflection signature searches are marked by dotted crosshairs (see text for references). The latitudes of two exemplary high-resolution spectrographs, CARMENES and ESPRESSO, are visualised as horizontal dashed lines, the declination ranges within which targets culminate at airmasses lower than 1.5 are shaded in the respective colour.
