Notes. Rows 4–7 apply only to stars with GDR2 kinematic information, and rows 8–10 apply to those without. From the top to the bottom row we list the number of stars with FLAMES/GIRAFFE spectroscopic observations, stars whose radial velocities have been determined, stars retained after the photometry-based cleaning, stars after parallax cut, and stars after proper motion cut. Rows 6 and 7 give the number of stars that we consider as certain or candidate members, respectively, when the l.o.s. velocity is also used as criterion. Row 8 lists the number of stars without GDR2 kinematic information; the last two rows list how many of them are certain and candidate members when the l.o.s velocity information is included.
