Post-processed contrast of the ERIS gvAPP in the Br-γ, Br-α, Br-α-continuum, and K-peak filters. The contrast curves for the first three filters were calculated after PSF subtraction with optimal PCA/ADI via fake planet injections. The contrast curve for the K-peak filter was calculated with the TRAP algorithm (Samland et al. 2021). The angular separation is shown in units of λ/D in order to compare the results for the different narrow band filters. The central wavelength and effective width of each filter are indicated in the label of each curve. The shaded area represents the uncertainty of the contrast curve.
