Properties of metal-rich populations. The first column shows the kinematical diagrams, where 
is the angle between the line of sight on the object and the vector of rotation about Z-axis, and VS is objects line-of-sight velocity relative to an observer at rest at the position of the Sun. The straight lines are regression fits, whose slopes yield the subsystem’s rotation rate. The second column shows the relations between metallicity and distance from the Galactic plane. The slope of the regression line yields the metallicity gradient. The third column shows the distributions of GCs and field RR Lyrae stars in Z. The curves approximate the histograms with an exponential laws with scale heights ZO.discussion in the text | privious figure | next figure
