Appendix A: Observational data

The observational log can be found in Table A.1 and the channel maps of all the observed lines toward the four sources are shown in Figs. A.1A.6.

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.

Appendix D: L1536

Figure D.1 shows the 12CO J = 3–2 spectral map obtained with JCMT, where there is no indication of classical bipolar outflows are present.
