870 μm continuum emission from Cycle 0 ALMA observations of G35.20. The continuum peaks are labeled in order of intensity (i.e., peak B1 has the highest and peak B3 the lowest continuum intensity). Contour levels are 0.03, 0.042, 0.055, 0.067, 0.08, 0.10, 0.13, 0.18, and 0.23 Jy beam⁻¹ (σ = 1.8 mJy beam⁻¹). The pixel-sized colored squares denote each of the spectral extraction points (from Allen et al. 2017).
