CH₃CN 6₂-5₂ (black), CH₃OH 2₁₁-1₀₁ (orange) and CO 2-1 (teal) spectra (in K) extracted in the four regions of the red-shifted (R1 and R2) and blue-shifted (B1 and B2) outflows of S68N. The spectral resolutions are 0.061 MHz (0.16 km s⁻¹) for CH₃CN, 0.122 MHz (0.14 km s⁻¹) for CH₃OH, and 0.384 MHz (0.5 km s⁻¹) for CO. The CH₃CN emission is multiplied by a factor 6.5 in R1 and R2, and by a factor 8 in B1 and B2. The CO emission is multiplied by a factor 0.02 in R1 and R2, 0.01 in B1 and 0.03 in B2 for visualisation purposes. The black dashed vertical lines mark the v_sys (+8.5 km s⁻¹, Lee et al. 2014).
