Locations of the OH absorption profiles, labelled by triangles. The magenta contours indicate the OH-streamer, the olive-coloured contours depict the +80 cloud, and the purple contours delineate parts of the +20  km s^-1 cloud, at 50, 85, and 32  km s^-1, respectively. The lowest contour level is at 3.5σ (90 mJy/beam), and the contour interval is 1σ spacing. Position numbers 1−10 belong to the OH-streamer, 11−13 are in the +80  km s^-1 cloud, and 14−16 are inside the +20  km s^-1 cloud.
