Notes. The columns are: GaiaDR3Id, Gaia DR3 Id number; Gaia-RA, RA (deg); Gaia-DEC, Dec. (deg); Gaia-G, Gaia DR3 G magnitude; Gaia-BP, Gaia DR3 G_BP magnitude; Gaia-RP, Gaia DR3 G_RP magnitude; plx, Gaia DR3 parallax; plx-err, Gaia DR3 error on the parallax; pmra, Gaia DR3 proper motion in RA direction; pmra-err, Gaia DR3 error on RA proper motion; pmdec, Gaia DR3 proper motion in Dec. direction; pmdec-err, Gaia DR3 error on Dec. proper motion; ellr, elliptical radius at which the star lies; Flamesfield, name of the VLT/FLAMES pointing; SpecName, name of object in VLT/FLAMES pointing; N-Spec, number of individual VLT/FLAMES spectra combined; SN, the signal-to-noise of the single (for N-Spec = 1) or combined VLT/FLAMES spectra; Vel, the v_los for this star measured from VLT/FLAMES spectra, averaged if N-spec> 1; vel-err, error on the v_los VLT/FLAMES measurement; vel-var, the variance of the VLT/FLAMES v_los if N-spec> 1; FeH, the [Fe/H] for the star determined from the CaT measurement from VLT/FLAMES spectra, averaged if N-spec> 1 ; feh-err, the error on the VLT/FLAMES [Fe/H] determination; feh-var, the variance of the VLT/FLAMES [Fe/H] if N-spec> 1; z, the Gaia DR3 membership score, as defined in Sect. 3.1; mem, the likely membership of the star in the Sculptor dSph where m is for member stars, b is for borderline members and n is for non-members; feh-rel gives the reliablity of the [Fe/H] determination, where 0 is for reliable [Fe/H] and 1 is for an unreliable [Fe/H], which should be used only with great caution, for non-member stars a CaT [Fe/H] has no meaning, and so these are given as – in this column and there are also no values given in the table. The non-members in Table E.1 are stars with VLT/FLAMES spectroscopic v_los compatible with membership in Sculptor but the Gaia proper motions and/or parallaxes ruled this out.
