Simulating METIS SCAO System
METIS, the Mid-Infrared ELT Imager and Spectrograph, is one of the four
first-generation ELT instruments scheduled to see first light in 2028. Its two
main science modules are supported by an adaptive optics system featuring a
pyramid sensor with 90x90 subapertures working in the H and K bands. During the
PDR and FDR phases, extensive simulations were carried out to support the
sensing, reconstruction, and control concept of METIS single-conjugate adaptive
optics (SCAO) system. We present details on the implementation of the
COMPASS-based environment used for the simulations, the metrics used for
analyzing our performance expectations, an overview of the main results, and
some details on special cases like non-common path aberrations (NCPA) and water
vapor seeing, as well as the low-wind effect.Comment: 17 pages, 14 Figures, AO4ELT VII Conference - Avignon - June 202
