Fig. 11
Averaged “recentered” spectra corresponding to the whole disk. Spectra are calculated from H i spectra recentered on the H i peak velocity (light blue) and from the CO cube recentered with the H i peak velocity (black and red), the H i emission moment velocity (green), and the analytical rotation curve velocity (dark blue). The H i spectrum is divided by 2500 to be compared with the CO spectra.
