Distribution of the difference between the current galactocentric position of stars and their guiding centres for the G3RV2 sample (red) and G3RV2 all stars in common with Galah, APOGEE, and LAMOST (GAL, blue; see Sect. 4) (left). Distribution of R − R_g for G3RV2 stars at different galactocentric radii (right). Shaded areas in the left panel correspond to 95% of the distribution around its maxima. The distributions suggest that most stars are found less than 2 kpc away from their guiding centres. The visible asymmetry of the distribution is caused by the contribution of accreted onto the MW stars (see Sect. 3.1 and Appendix A for details).
