Completeness of the VLT/FLAMES LR8 survey relative to Gaia DR3 for Sculptor members as a function of elliptical radius (r_ell): (a) the number of Gaia DR3 astrometric members (solid black line), and those with VLT/FLAMES LR8 spectroscopic confirmation (dashed red line), with a black dotted line at null; (b) fraction of Gaia DR3 astrometric members that have a VLT/FLAMES LR8 spectrum of sufficient S/N, > 7, and a v_los consistent with membership. The dotted black line denotes 70%.
