S68N outflows and its analysis. Left panel: 2.7 mm continuum (greyscale) with overlaid redshifted and blueshifted emission of CH₃CN 6₂ − 5₂ (salmon/cyan shaded contours) and CH₃OH 2_−1, 1 − 1_0, 1 (red and blue contours). Contours start at 2σ in steps of 1σ (σ = 60 and 50 mJy beam⁻¹ km s⁻¹ for CH₃CN and CH₃OH, respectively). Black circles label the analysed regions (R1, R2, B1, B2); stars mark protostellar positions. The dashed circle indicates the CH₃OH primary beam and synthesised beams are shown at the bottom-right. Right panel: CH₃CN rotation diagrams in the four labelled regions. Colour coding is the same as in the left panel. Derived column densities and rotational temperatures are reported.
