Integrated intensity map of the ¹³CS 5–4 transition with colored scale, shown as a bar above the figure. The boundary contour in black is for the 0.15 Jy beam⁻¹ km s⁻¹ intensity, and the white contours are for the 0.15 × [3, 5, 7] Jy beam⁻¹ km s⁻¹ intensities. The magenta contour lines show the H30α line with a scale of 0.5 × [1, 2, 3, 4, 5] Jy beam⁻¹ km s⁻¹. The labels A1–A13 are the positions of the dust continuum peaks identified by Liu et al. (2015). The beam of 0.″75 × 0.″60 (﹩\mathrm{PA}=88^\circ ﹩) is shown in the bottom left corner.
