Notes. Best-fit results of the spectra shown in Fig. 8. Coordinates of the spectra are listed in offset with respect to (RA, Dec), +30°33′0430). VLSR, TB and  △ v is the observed velocity with respect to the local standard of rest, the brightness temperature and the line-width, respectively. θPA is the position angle of the offset location with respect to the major axis of the disk (− 121.3° from north), assuming an inclination of 23°. Values in brackets are fixed. Note that there is no robust 13CO  detection at locations CO S2E to CO S2J.
