In the process of rounding off the results homogeneously obtained within the model-comparison phase of the Basle Halo Program, space densities of both photometric populations, I and II, have been derived, for late-type giants and for main-sequence stars with M(G) in the +3 to +8 exp m range, in a field close to the globular cluster M 5, according to the RGU-photometric Basle method (Becker, 1965). Compared to the density gradients predicted by the standard set of five multicomponent models, used since the beginning of this phase (del Rio and Fenkart, 1987), they confirm the existence of a Galactic Thick Disk component, in this direction, too.
