ALMA maps of G336.01–0.82. (a) Continuum map at 1.3 mm. The position of the three local continuum peaks is indicated by the green labeled triangles. The contour levels are −3, 5, 10, 20, 40, 80 × σ _rms with σ _rms = 55 μJy beam⁻¹. (b) HC₃N J = 24 − 23 l = 1f, v ₇ = 1 zeroth moment map contours over the continuum map. The contours are 5, 8, 10, 15, 20, 25 × σ _rms with σ _rms = 11 mJy beam⁻¹ km s⁻¹. (c) SiO J = 5–4 blue- and redshifted, and the contour levels are 5, 6, 7 ... 12 × σ _rms with σ _rms = 7.7 mJy beam⁻¹ km s⁻¹. Velocity integration ranges with respect to the systemic velocity are annotated by the respective color. The beam size of the continuum map is shown in the lower left corner.
