Spectra extracted at [Δα, Δδ] = [+094] from the MSR data sets for the J = 2 − 1 line of CO (left panel) and the J = 3 − 2 line of CO (right panel) in yellow-filled histograms; these spectra were extracted using a common aperture of ≃6–7 pc. We also show in blue-hatched histograms the corresponding spectra obtained from the HSR data sets using a common aperture of ≃2–3 pc. The green line highlights the radial velocity predicted by kinemetry, which accounts for the contribution of a co-planar outflowing component (v_kin). We also indicate by the red line the radial velocity due to circular motions predicted by the kinemetry best-fit model (v_cir).
