All Tables

Table 1: Source sample^a.
Table 2: Observed transitions.
Table 3: Observed line fluxes $\int T_{\rm{MB}} {\rm d}V$ (K km s^-1) from Gaussian fits, and 1 $\sigma$ upper limits^a.
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.
Table 5: Observations of CS, C³⁴S and C¹⁷O lines towards MonR2 IRS3.
Table 6: Rotation temperatures (K). Numbers in brackets denote uncertainties.
Table 7: Column densities (cm^-2) in 15-20'' beams.
Table 8: Power law model $n=n_0(r/r_0)^{-\alpha }$ for the density structure of MonR2 IRS3.
Table 9: Molecular abundances and abundance ratios: outer envelope.
Table 10: Models with SO₂ abundance "jumps''.
