Distribution of α as a function of v for known members of the Pleiades SKG, as seen from two likely candidates (α_MG ≳ 200°) from a first estimate. The gray shading denotes the area of ± 4σ around the mean angle, while the dashed and long-dashed lines delimit the area if we use a 3σ clipping and a 5σ clipping, respectively instead. Known members fulfilling this angle criterion are displayed as dots, while the diamonds are used for disregarded ones. The adopted α_MG, written at the top of each panel, is shown by an arrow.
