Notes. Column (1) field Tuc0 and Tuc1; (2) slit aperture: numbers < 30 indicate observed targets from chip-1, otherwise from chip-2 – numbers counted from bottom to top of the CCD; (3) RA-Dec coordinated in J2000; (4) V band magnitude with error from VLT/FORS2 photometric catalog; (5) I band magnitude with error from same catalog; (6) l.o.s. heliocentric velocity with error; (7) metallicity with error; (8) S/N in pxl−1 (the conversion factor to Å−1 is 1.09); (9) probability of membership – the three columns indicate the probabilities obtained using the P91 dataset alone (P1), combining with the P69 (P2) and further adding the FLAMES data (P3). Four stars had repeated measurements: targets 31, 32, 33, and 35 from Tuc0 field corresponding to targets 31, 32, 33, and 36 from Tuc1 field, respectively; in this table, we report the single measurements as well as the averaged values used during the analysis process. In the P columns, stars marked as “Ph” are nonmembers, excluded according to their magnitudes and colors, or because they lack reliable measurements (see Sect. 4 for full description).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
