Notes. Column (1) slit aperture: numbers < 30 indicate observed targets from chip-1, otherwise from chip-2 – numbers counted from bottom to top of the CCD; (2) RA-Dec coordinated in J2000; (3) V band magnitude with error from VLT/FORS2 photometric catalog; (4) I band magnitude with error from same catalog; (5) l.o.s. heliocentric velocity with error; (6) metallicity with error; (7) S/N in pxl−1 (the conversion factor to Å−1 is 1.08); (8) probability of membership according to the best-fitting kinematic model – the three columns indicate the probabilities obtained using the P69 dataset alone (P1), combining with the P91 (P2) and further adding the FLAMES data (P3). In the P columns, stars marked as “Ph” are nonmembers, excluded according to their magnitudes and colors, or because their measurements proved to be unreliable (see Sect. 4 and Appendix A for full description).
