Integrated line wings of ¹³CO emission (blue and red) around NGC 2071 obtained with the SMA. It is overplotted on the 1.3 mm continuum emission (grayscale) in steps of 3, 6, 9, 12σ (see van Kempen et al. 2012). Locations of continuum sources (A, B, and C) are labeled. The beam size of 3.4′′ × 2.9′′ is shown in a black ellipse in the lower left. Dashed circles indicate the regions integrated for organic emission, including region F (see text).
