... contamination

An additional argument in favor of only a very faint background contribution in the AMBER UT observation can be found in the shape of the high spectral resolution line: the light from the speckle objects B, C, and D is produced in areas with velocities smaller than 50 km s^-1. Therefore, it produces a narrow emission line which should appear in the center of the broad Br$\gamma$ line. Just looking at the shape of the line, it can be concluded that such an effect is negligible.

... emission

For a qualitative sketch of the geometry, see "zone 4'' in Fig. 8 of Martin et al. (2006), even though this figure was drawn to represent He⁺⁺ in a different context. For reasonable densities, the predicted He⁺ zone has a quasi-paraboloidal morphology. In addition, some extremely dense cooled gas, labeled "zone 6'' in the same figure, may also produce He I emission.
