Velocity-integrated maps of CS, H₂S, and SO, which show extended emission throughout the CMZ with their peak of intensity towards the inner CMZ. The positions of TH2 (Turner & Ho 1985) and the kinematic centre (Müller-Sánchez et al. 2010) are labelled by a filled magenta star and triangle, respectively. The regions where the spectra were extracted are shown by the magenta circles and are labelled in the left-most panel. The beam is depicted in the lower left corner of each plot. The scale bar of 100 pc corresponds to ∼6″. Top: velocity-integrated maps of CS (2–1), (4–3) and (6–5). Levels start at 3σ (1σ = 46, 150, and 148 mJy.beam⁻¹, respectively; white contours) with steps of 30, 30, and 50σ (black contours), respectively. Middle: velocity-integrated maps of H₂S (1_1, 0 − 1_0, 1), (2_2, 0 − 2_1, 1) and (3_3, 0 − 3_2, 1). Levels start at 3σ (1σ = 79, 50, and 81 mJy beam⁻¹, respectively; white contours) with steps of 15, 40, and 30σ (black contours), respectively. Bottom: velocity-integrated maps of SO (3₄ − 2₃) and (3₅ − 3₄). Levels start at 3σ (1σ = 50 and 28 mJy.beam⁻¹, respectively; white contours) with steps of 7 and 3σ (black contours), respectively.
