Open Access

Fig. A.1.

NIRSpec IFU PSF at 4μm as traced by the quasar Hβ broad-line flux. The location of the peak of the quasar is marked as an orange cross, with the 0 $\overset{″}{.}$ $\overset{\prime \prime }{.}$ 35 radius aperture used to integrate the quasar spectrum shown as an orange circle. The black ellipses are the same as in Figure 3 to aid in a spatial comparison to the extended galaxy emission.
