Sculptor members in the VLT/FLAMES LR8 sample (red), as well as all Gaia DR3 Sculptor members selected on the basis of parallax and proper motion only (yellow-green colour coding): (a) on the sky, where the black ellipse indicates the nominal tidal radius and the blue arrow the direction of proper motion of Sculptor in the plane of the sky; (b) in proper motion; and (c) and (d) in the CMDs. The larger black symbols indicate the borderline cases between non-members and members identified in Fig. 11.
