Diagram of the knot 16 complex with all identified features. Top: 2-color continuum-subtracted image of the knot 16 complex, with HST [FeII] emission in green and LUCI-1 SOUL AO H₂ emission in blue (see Fig. 4f for reference). Sub-knots are labeled along with knot 18. Sub-knots of the knot 16 complex are identified first in [FeII] and then in H₂. Bottom left: significance level contour map for the sub-knots identified in the knot 16 complex from the continuum-subtracted [FeII] data (gray scale image). The contour levels represent values from 5 to 500σ, in steps of 55σ, where σ is the standard deviation sampled from the local background (see Sect. 3.3.2) Bottom right: significance level contour map for the sub-knots identified in the knot 16 complex from the continuum-subtracted H₂ data (gray scale image). The contour levels represent values from 5 to 45σ, in steps of 5σ, where σ is the standard deviation sampled from the local background (see Sect. 3.3.2). North is up and east is to the left in all panels.
