$^a$ Main beam brightness temperature from gaussian fit. $^b$~{\it FWHM} from the hyperfine fits. $^c$ optical depth of the main group of hyperfines from the hyperfine fits.

 Note: Five sources clearly have at least~2 velocity components, hence the fit parameters have been determined for each component. Similar notations are used for other molecules elsewhere in this paper. The parameter has been fixed for the fit for those entries with no error indicated.
