Overlay of the 870 μm continuum emission (red contour) on the integrated intensity maps (colors) of C¹⁷O, C³⁴S, H¹³CO⁺, and SiO. The contour level of the continuum emission corresponds to the 9.0 mJy beam^-1 intensity (see Fig. 1). The intensity scale for the integrated emission for each molecule is shown in the color bar at the right of each panel, in K km s^-1. The synthesized beam of the continuum emission (, PA = 46°) is shown in the bottom-left corner of each panel. For each molecule, we show the synthesized beam of the tapered maps in the bottom-right corner: a) , PA = 67°; b) , PA = 67°; c) , PA = 69°; and d) , PA = 69°.
