Fig. 4.
Channel maps of the CND (red dashed ellipse) and its surrounding region in the SiO v = 0, J = 2–1 emission line. The central velocity range is from Vc, LSR = −142.5 to +147.5 km s−1, and the velocity width of each panel is 10 km s−1. The angular resolution is |${2.^{\prime \prime }5} \times {1.^{\prime \prime }8}$| in FWHM, which is shown as the oval at the lower-left corner of each panel. The contours in the figure show the continuum emission of the GCMS at 100 GHz for comparison (Tsuboi et al. 2016). They are set at 3.75, 7.5, 15, 30, 60, 120, 240, 480, and 960 mJy beam−1.
