Integrated intensity maps of the observed transitions: (a) CH₃OH, (b) CH₃CN (all K transitions together), (c) OCS, (d) H₂S, (e) SO₂, and (f) SiO. Intensity scales of the false color (in units of Jy beam⁻¹ km s⁻¹) are shown above each panel. White contour lines have been included in the panels for clarity in addition to the false color image. Contour levels (in unit of Jy beam⁻¹ km s⁻¹) are: 0.05, 0.1, and 0.15 for (a), 1.5, 4.5, and 7.5 for (b), 0.05, 0.1, and 0.15 for (c), 0.4, 0.6 and 0.8 for (d), 0.04, 0.08, 0.12, and 0.16 for (e), and 0.4, 0.8, and 1.2 for (f). Beams are shown in the bottom left corners. The black contour is the outline of the ¹³CS 5–4 emission in Figure 1.
