Completeness of the VLT/FLAMES LR8 survey relative to Gaia DR3 for Sculptor members as a function of Gaia G magnitude: (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) the fraction of Gaia DR3 astrometric members that have a VLT/FLAMES LR8 spectrum with S/N > 7 and v_los consistent with membership in Sculptor. The black dotted line denotes 70%.
