A preliminary design review study of the scientific performance of MAORY (MORFEO)

For the aims of the Preliminary Design Review process, we produced a set of numerical simulations intended to investigate the performance of the MAORY multi-conjugate adaptive optics (MCAO) module of the ELT. After this successful review we renamed officially the instrument as Multiconjugate adaptive Optic Relay For ELT Observations - MORFEO. We present the analysis performed adapting the SimCADO tool for generating simulated MORFEO corrected observations as imaged through the MICADO camera. The PSFs were beforehand computed using the PASSATA code adopting realistic atmospheric profiles. We performed analysis on different scenarios including partially resolved structures. We also performed specific simulations to assess the contribution of the residual spatial variation of the MCAO PSF to the astrometric error budget.
