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.1–A.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 11_1₁1−10_00₁₀ (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.

	Fig. C.3 Moment 0 maps of C¹⁸O J = 2–1, SO 5₆–4₅ and SO₂ 11_1₁1−10_00₁₀ toward all sources from the WideX data. The contours are drawn at 10% of the peak starting at 3σ. Green star indicates the continuum position and black ellipses show the synthesized beams.

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.

	Fig. D.1 ¹²CO J = 3–2 spectral map obtained with the JCMT from –5 km s^-1 to 15 km s^-1 and intensities from –0.5 K to 3.5 K. The vertical dotted lines show 0, 5.2, and 10 km s^-1 for guidance.
