LBT LUCI K_s (top-left, data from Bik et al. 2012) and Spitzer IRAC 4.5 μm (bottom-left) continuum maps, as well as integrated emission in the blue (top) and red (bottom) line-wings of combined NOEMA and 30 m maps of ¹³CO 2−1 (middle) and SO 6−5 (right). The NOEMA continuum emission with natural weighting is shown as green (left) or grey (middle and right) contours from 5 to 30σ in 5σ intervals (σ = 0.95 mJy beam⁻¹). The velocity integration windows for the ¹³CO and SO maps are indicated in the right-hand panels. The purple arrows indicate the tentatively identified direction of the outflow, with dashed lines used to highlight features which may trace the outflow cavity walls (see text for details).
