Appendix B: Large-scale structure
The parameters of the large-scale envelope structure used to estimate the continuum emission at short baselines are in Table B.1.
1D spherical envelope parameters as published by Kristensen et al. (2012).
Appendix C: WideX data
Spectra toward all sources integrated within a 3″ box around their continuum positions are shown in Fig. C.1. The integrated flux density maps toward C18O, SO 56−45 and SO2 11111−100010 (221.96521 GHz) are shown in Fig. C.3. The SO emission toward all sources is much more extended compared to the C18O emission, while the SO2 emission is compact.
