Upper panel: synthetic spectrum of CH₃OH fitted to the MM1 data. The black histogram is the observed spectrum, overlaid with the red fit whose parameters are listed. Blue lines mark transition frequencies, and confirm that lines at 217.299 GHz, 217.643 GHz, 217.886 GHz are CH₃OH. Lower panel: intensity integrated maps over the velocity range from −65 to −50 km s^-1 (V_lsr ~ −60 km s^-1 in MM1), with red contours showing the 3σ rms. White contours show the continuum (at 4σ, 14σ, and 24σ levels), purple contour reveals the region where molecular specific intensity > 3σ.
