The trajectory of a typical disk star (the Sun) in cylindrical coordinates (
, Z). RP is the perigalactic radius and Ra, the apogalactic radius. Zmax is the maximum deviation of the star from the Galactic plane. THe dotted curve shows the position of the Galactic plane. The hatched horizontal band shows schematically the band in Z, where the probability of that location of the star was calculated. The vertical band shows the width of the column in which we reconstruct the star distribution in Z.discussion in the text | next figure | previous figure
