Notes. The intrinsic/extrinsic nature is indicated by a capital letter (I/E) in the third column when it derives from Tc detection/non-detection (second column). Indeed Tc detection is an unambiguous diagnostic of on-going nucleosynthesis, and therefore an intrinsic star marker. Conversely, S stars classified as intrinsic or extrinsic on the basis of multivariate classification (Table 4 of Van Eck & Jorissen 2000a) are flagged by a lowercase letter (i/e). The lowest χ2 value (Eq. (2)) is listed in column labelled . The Teff, log g, C/O, [s/Fe] and [Fe/H] values between braces represent the parameter range covered by the various best-fitting model atmospheres, having 
(see Sect. 4.2.1). Stars with unusually blue colours might have spurious high gravities; they are flagged with a colon (:). In column “Rem.”, Hα emission is indicated, LaO stands for detection of LaO absorption bands, and Li for an abnormally strong Li line.
