**Table 4:** Widths $\Delta V$ (km s^-1) of the emission line components, averaged over transition. Numbers in brackets denote uncertainties in units of the last decimal, except when only one transition was observed. Dots denote missing data. For SO, values for the narrow and the broad components are reported, whose positions are also given.
