Notes. We compare the effective PSF of SINFONI and ERIS to demonstrate the stability of the PSF in combination with the resulting quality after stacking individual data cubes to a resulting mosaic. The listed values here are to be compared with the independently measured quantities in Table A.1. As is evident, the yield from short on-source integration observations using ERIS is high.
