PSF for HARMONI in the instrument configuration summaries in Table 3 at three wavelengths ranges. Upper panels: filter-band images (0.89−0.92 μm (left), 1.26−1.31 μm (centre), and 1.67−1.73 μm (right)). The 20 × 20 mas² scale of our mock HARMONI observations undersamples the potential FWHM of the PSF, which varies from ∼6 mas at the bluest filter to ∼11 mas at the reddest one. Intensities are in logarithmic scale and normalised to the peak in each case. Lower panels: radial profiles along the right ascension axis and through the centre obtained from the filter-band image of the lenticular host galaxy scaled to 10¹¹ L_v, ⊙ without QSO (black profile), the QSO of L_[OIII] = 10⁴² (red dashed-profile), and the QSO of L_[OIII] = 10⁴³ (blue dotted-line). Intensities are normalised to the peak of the host in each case.
