Distribution of the peaks (colored points) obtained by fitting a 2D Guassian to the emission in each channel of the channel maps of the CH₃CN(12–11) K=3 line. The colored ellipses are the deconvolved FWHM of the fitted Gaussians. The color corresponds to the LSR velocity as indicated by the scale to the right. The black cross and ellipse represent the peak position and deconvolved FWHM of the 1.4 mm continuum emission, respectively. The dashed line outlines the direction of the major axis of the black ellipse. The shaded ellipse in the bottom right corner represents the synthesized beam.
