Rectangular Galactocentric X versus Y distribution of our selected targets. The grey area represents the approximate position and shape of the Galactic bulge. The Sun is indicated at (X,Y)=(8.2, 0) kpc. Left: selected targets with peculiar velocities higher than 200 km s⁻¹ relative to LSR are represented with open symbols, while the others are represented with filled symbols. Right: red arrows represent the tangential velocities, , of the targets, which are colour-coded for their absolute velocities perpendicular to the plane, V_ɀ. The colour code is identical to that of Fig. 16 with large dots and circles representing HdC stars and down triangles representing the EHe stars.
