Map of the locations of the different velocity profiles in the south (left) and north (right) where spectra are fit with single (open circle), double (filled circle), triple (triangle), or more (square) components (see for comparison Fig. 2). The size of the symbol is scaled to the integrated CO intensity, while the gray scaling indicates the effective velocity width of the profile shown by the scale bar to the right (estimated by summing the ΔV measured for each individual component in quadrature). The same scaling is adopted for the northern and southern bar ends.
