Line-to-continuum ratio plots of H₂, [Fe II], and Br-γ emission. Intrinsic emission appears bright in these images, whereas scattered light is represented by a constant ratio close to unity. The source position is represented with a red plus symbol. A signal-to-noise threshold, set at three times the background noise, is implemented in these images to reject background emission, meaning the morphologies one sees in these figures is due to a combination of the continuum and the intrinsic line emission. Top left: Integrated H₂ emission between −140 km s⁻¹ and +60 km s⁻¹ divided by nearby continuum. The intrinsic line emission here comes from the cavity walls and a H₂ knot at the base of the left cavity wall (A1). Top right: Integrated [Fe II] emission between −310 km s⁻¹ and −100 km s⁻¹ divided by nearby continuum. The intrinsic line emission here traces the high-velocity atomic jet. Bottom left: Integrated high-velocity Br-γ emission between −230 km s⁻¹ and −130 km s⁻¹ divided by nearby continuum. The intrinsic line emission here again traces the high-velocity atomic jet. Bottom right: Integrated low-velocity Br-γ emission between −100 km s⁻¹ and +100 km s⁻¹ divided by nearby continuum. There is no spatially extended intrinsic emission detected here.
