$^a$ The ratio between the intensities at the central velocity of the
line and at the velocity of the horns (i.e. maximum blue or red
shifted emission); $^b$~fixed to values obtained for the C$^{34}$S or
Si$^{34}$S lines; $^c$~simultaneous fit with a blended, unidentified
line at~$\nu=103.2804$~GHz and an intensity of~46(18)~K~km~s$^{-1}$; $^d$ From the integrated intensities yielded
by the fits to the lines of~$^{34}$S- and~$^{36}$S-bearing species.
The error given is the 1~$\sigma$~error from the fit and does not
contain an estimate of systematic errors, e.g. due to baseline
uncertainties.
