Profiles of the line emission plotted along the axis of the cone-shaped nebula (the offset axis is measured in the plane of the sky). In the top panel we present profiles of [FeII], H₂ 1−0 S(1), and H₂ 2−1 S(1) in red, blue, and green, respectively. In the bottom panel we show the profiles of CO 2−0 (bh) and Brγ in red and blue, respectively. In both panels, the continuum emission in K band, observed with the K-cont filter (black), is included for comparison. The profiles are normalized to the peak emission.
