Integrated intensity (first column), centroid velocity (middle column) and velocity width (right column) of the NH₃ (1,1) transition (top row) and NH₃(2,2) transition (bottom row). The NH₃(1,1) data were masked to 5σ, while the weaker NH₃(2,2) data were masked to 3σ. Filaments are named in the top left panel. Contours in the top left panel are in steps of 7 K × km s⁻¹, from 5 K × km s⁻¹ to 61 K × km s⁻¹, while contours in the bottom left panel are in steps of 1 K × km s⁻¹, from 1 K × km s⁻¹ to 6 K × km s⁻¹. Beam information is plotted in the bottom right corner of each panel, while the scale of 1 pc is plotted in each panel of the top row.
