Para-NH₃ (1,1) intensity-weighted mean velocity (moment 1, left) and FWHM line width (moment 2, right) maps. The reference position is l = 28.59°, b = 3.55°. These intensity-weighted mean velocities and FWHM line widths referring to the individual hf components are derived from the GILDAS built-in “NH₃ (1,1)” fitting method (Sect. 2.2). The considered velocity range is 4 < V_LSR < 10 km s⁻¹ for each panel. Contours of integrated intensity start at 0.23 K km s⁻¹ (5σ) on a main beam brightness temperature scale and go up in steps of 0.23 K km s⁻¹.
