Left panels: inverse radial scalelengths for all subpopulations adopting the LSR V_⊙ = 3.06 km s^-1 (best fit in the lower panel of Fig. 5, top panel), 5.25 km s^-1 (Aumer & Binney 2009, middle panel), and 12.24 km s^-1 (Schönrich et al. 2010, lower panel) with colour-coded metallicity. Right panels: radial scalelengths for the same data. For the Schönrich value of the LSR (lower panel), the absolute values | R_ν | are plotted in logarithmic scale with negative values marked as crosses.
