Relations between the residual spatial velocityand other characteristics of the RRLyrae stars.The filled circles represent stars with [Fe/H ] > -0.95; the large open circles with error bars are mean values and dispersions of the corresponding parameters in narrow intervals of Vres. The vertical and slanted dashed lines in the first panel mark the separation distinguishing are as occupied by thick-disk objects according to Hanson et al. (1998) and Martin, Morrison (1998), respectively. An abrupt change in the dispersion near Vres
290 km/s (the vertical dashed lines) is apparent in all panels except the first.
