Figure 4
C17O (2–1) line spectra taken with the JCMT. The frequency of this transition is 224.71 GHz and the spectral resolution is 0.24 km s−1. The line profile positions are with respect to the centre of Fig. 1 and each line profile is offset from each other by 10 arcsec. The red solid line is the data and the black dashed line is the model.
