Line of sight and distances probed projected on the Galactic plane as seen from the north Galactic pole. The background is the Fux (1999) disc/bar particles within 500 pc from the Galactic plane translated to R0 = 7.6 kpc and with an angle φbar = 26° relative to the Sun-galactocentric line of sight. To guide the eye, the dotted line represents a straight bar of radius 2.5 kpc and with an angle φbar = 26°. The green full lines correspond to our sample locations (corresponding to 68% HDI of the distance distribution of each sample). The black circles correspond to the density peak of Babusiaux & Gilmore (2005). The red diamonds indicate the distance of the change in mean radial velocity used here to constrain the bar angle.
