Schematic view of the 50 km s−1 cloud. It is one of the closest cloud complexes to the GC. Following Lee et al. (2008) we show the relative locations of some of the clouds that are quite close to the LOS. The circumference of the 50 km s−1 cloud and its possible extension have been indicated in light blue. In the right panels, the radial velocity vector is shown as a narrow peak pointing towards the observer. In the left panels, the radial velocity vector is shown as a solid horizontal vector pointing towards the observer. The approximate linear scale is indicated. Top panel: situation if the 50 km s−1 cloud and its extension have proper motions towards the NW (bold solid line) or SE (bold dashed line). We have drawn the radial and proper motion vectors (and their projections) in both top panel views. The direction perpendicular to the orbital plane of the bypassing 50 km s−1 cloud complex is shown as a short dashed line. Bottom panel: situation for a proper motion in NE (bold solid line) or SW (bold dashed line).
