N₂H⁺(1−0) integrated intensity emission from Hacar et al. (2018) in colour scale and black contours, with superimposed 5σ contours of the velocity-integrated emission of CH₃OH (5_1,4 − 4_1,3 A) (left) and CS (right) from this work. N₂H⁺ contours are equally spaced every 1 Jybeam⁻¹ km s⁻¹. The CH₃OH and CS contours are shown at 5σ with σ = 12.3 mJy beam⁻¹ km s⁻¹ and 23.2 mJy beam⁻¹ km s⁻¹, respectively. The different cores are depicted with magenta stars and are labelled in white. The direction of Fibre 43 is shown with a green line. The synthesised beams of N₂H⁺, CH₃OH (left), and CS (right) are depicted in the lower left corner in green and white, respectively.
