Planar cut in the 3D distribution of differential color excess for an inclined plane that does not contain the Sun. The image is centered on the location defined by the spherical coordinates (l, b, d) = (180.4°, 0°, 104 pc). The plane is inclined by 17.4° with respect to the Galactic plane and the longitude of the ascending node is l = 296.1°. It corresponds to the Gould Belt plane defined by Perrot & Grenier (2003). The units are mag pc⁻¹. The coordinates of the four axes are indicated in white boxes. The ellipse found by Perrot & Grenier (2003) to best represent Gould belt clouds and motions as an expanding and rotating structure is superimposed (dashed red line). For this plane the boundary of our computational volume is reached at about 1 kpc along the Y-axis.
