Monochromatic theoretical PSF of the gvAPP used in ERIS (from Boehle et al. 2021). It produces two coronagraphic images, each with a D-shaped dark hole from 2 to 15 λ/D. A third non-coronagraphic PSF 2% leakage term is generated for astrometry and photometry, as well as other spots for astrometric reference.
