It will provide a wide-field correction for the first-light instrument MICADO. The Low-Order wavefront modes will be sensed on 3 Natural Guide Stars with Shack-Hartmann Wavefront Sensors, so-called the LO WFS. In the presented work, we focus on the numerical study of the main aspects that depend on the LO WFS design and operational use: low-order sensing performance and sky coverage.ELETTRONICOenConference paper10.1117/12.23131752-s2.0-85053490559000452819300125https://www.spiedigitallibrary.org/conference-proceedings-of-spie/10703/2313175/LO-WFS-of-MAORY-performance-and-sky-coverage-assessment/10.1117/12.2313175.short2018SPIE10703E..46PFIS/05 - ASTRONOMIA E ASTROFISICA
