Density of the stellar RASS sources with respect to the Gould Belt. The A and B axes are located in the plane of the Gould Belt and directed as the semi-major and semi-minor axis, the C axis is directed perpendicular to the Gould Belt. The color scales with the density of the stellar RASS sources. The red line shows the position of the Gould Belt as defined by Guillout et al. (1998b) and the crosses indicate the positions of known stellar clusters.
