Minimum distance in colour–magnitude space of each bona fide single star in the Pleiades from the best-fitting isochrone plotted against the absolute magnitude (lower abscissa) and colour (upper abscissa) on the isochrone. A positive residual corresponds to stars that are brighter (redder) than predicted by the isochrone. A negative residual corresponds to stars that are fainter (bluer) than the isochrone. The uncertainty for each source in G_abs corresponds to the Gaia uncertainty in absolute G magnitude, and the uncertainty in the residual corresponds to the quadratically added uncertainties in absolute G magnitude and BP − RP colour.
