In each panel, the spatio-kinematics of the indicated line(s) is (are) shown on the 0.89 mm continuum image from Figure 1(a) (pixel size 50 mas), zoomed in toward MM1. Each plotted symbol shows the location of the peak emission from a 2D Gaussian fit in each channel (≤0.21 km s−1wide; the symbols are color-coded by velocity). The fitted relative position uncertainty is 20 mas, while the absolute uncertainty is twice that. Each panel also shows an ellipse representing the deconvolved size (FWHM) of the millimeter continuum emission from MM1 (Table 2). Panels (a–c) show CH3OH maser lines from SMA, panels (d–f) show CH3OH maser lines from ALMA, and panels (g–i) show thermal CH3CN J = 11−10 lines from ALMA. Symbol size is proportional to intensity on the same relative scale within each row; for SMA the maser symbol size is one-third the ALMA maser symbol size. Panels (g–i) also show position angle vectors (dashed) of −33.°0, −21.°0, and −5.°0, respectively.
