RVS spectra of 916 solar-analogue candidates from GSP-Spec (panel a) where 95% of GSP-Spec candidates satisfy G < 11.7. We also show the solar-analogue candidates obtained from a possible selection from GSP-Phot results in panel b, but we only show 1985 GSP-Phot candidates with G < 11.7. For comparison, panel c shows RVS spectra of 7589 randomly selected stars (i.e. no solar-analogue candidates) also with G < 11.7. In all panels, the red line shows the median in each pixel and the shaded red contours show the pixel-wise central 68% and 90% intervals. The solid blue line is identical in all three panels and shows the mean RVS spectrum of 13 solar analogues known from the literature.
