Fig. 2

OH absorption at 1667 MHz towards the inner ~110′′ (~4.4 pc) of the GC at velocities between −29 and 94 km s-1. The lowest contour level is 75 mJy/beam, ~3σ, and the contour spacing is ~3σ. The position of Sgr A* is marked with a plus sign. The OH-streamer is seen at velocities between −29 and 67 km s-1, the +80 km s-1 cloud at velocities from 76 to 94 km s-1, and the CND SW lobe between −29 and 15 km s-1. The three parts of the OH-streamer are labelled in the 67 km s-1 panel. The SS and the +20 km s-1 cloud can be seen south of Sgr A∗ in the 24 to 41 km s-1 panels, and are most prominent at 32 km s-1. The beam size is shown in the lower left corner of the uppermost left panel.
