Integrated intensity (zeroth moment) maps of NH₃ (1, 1) (left) and (2, 2) (right). The integration range of each panel is 6.5 < VLSR < 12.5 km s⁻¹. Contours start at 0.96 K km s⁻¹ (4σ) on a main beam brightness temperature scale and go up in steps of 0.96 K km s⁻¹. The limits of the mapped region are indicated with green dashed lines. A blue star in each panel indicates the Trapezium cluster and black filled circles in the lower right illustrate the half-power beam size.
