The distributions of apparent magnitude of the Besançon model in the u, g, r, i, and z bands around the NGP. The thin disc, thick disc, and halo are plotted as dotted lines (red), dashed lines (cyan), and dot-dashed lines (green), respectively. The solid lines (black) represent their sums. The error bars (blue) show data from SDSS DR7 for comparison. The samples of the u and z band data are selected in colour intervals of −0.2 ≤ (u − g) < 2.0 and −0.2 ≤ (i − z) < 0.5, respectively. The other colour ranges extend from −0.2 to 1.2 (see second column in Table 5). (A colour version is available on-line.)
