Trends in as a function of the cartesian coordinates (X′,Y′) centered on the Sun, with the Galactic center at (X′,Y′) = (−8 kpc,0). These are computed for particles inside a sphere of radius 3 kpc, when the Sun is placed at (R,φ,z) = (8 kpc, − 20°,0) and for the default bar model. The plotted data are averaged inside bins of 100 pc size in (X′,Y′), box smoothed on a scale of 200 pc. The contours enclose 90% of particles with −1.5 kpc <z< 0 (black) and 0 <z< 1.5 kpc (red), when the RAVE selection function is applied.
