Velocity-integrated images of CH₃NH₂. The kinematic centre (Müller-Sánchez et al. 2010) is labelled by a white triangle. The regions where the spectra were extracted are shown by the black and white circles and are labelled in the left-most panel. The beam is depicted in the lower left corner of each plot. The scale bar of 100 pc corresponds to ∼6″. Left: Velocity-integrated map of CH₃NH₂ (1_1,5−1_0,5). Levels start at 3σ (1σ = 42 mJy beam⁻¹ km s⁻¹) with steps of 3σ. Right: Velocity-integrated map of CH₃NH₂ (3_−1,1−2_0,0). Levels start at 3σ (1σ = 42 mJy beam⁻¹ km s⁻¹) with steps of 3σ.
