Reddening and metallicity maps of the Milky Way Bulge from VVV and 2MASS. I.The method and minor axis maps
Galaxy: bulge - ISM: dust, extinction - stars: abundances

The Milky-Way bulge is studied through calculating the galactocentric
orbits of imaginary bulge stars for initial conditions simulating the bulge.
