Moment maps (moment 0, 1, and 2 in the left, centre, and right panels, respectively) of DCN (3-2) emission towards the protoclusters G008.67 (top), G010.62 (middle), and G012.80 (bottom). All three moments have been determined over a velocity range of 31.7 to 43 km s⁻¹, −9.3 to 5.8 km s⁻¹, and 30.7 to 43 km s⁻¹ for G008.67, G010.62, and G012.80, respectively. For the moment 0 and moment 2 maps, we overlay the core positions and sizes (red ellipses) from the continuum core catalogue described in Louvet et al. (2023). For the moment 1 and moment 2 maps, we show a zoom-in of the area highlighted by the yellow dashed box overlaid on the moment 0 map. The moment 1 and moment 2 maps have an additional threshold cut per channel of 4 σ. The synthesised beam is shown in the bottom left corner of each image.
