The Giant Magellan Telescope natural guidestar adaptive optics mode: improving the robustness of segment piston control

Astronomical Telescopes + Instrumentation, 2022
The Natural Guidestar Adaptive Optics (NGAO) system of the Giant Magellan Telescope (GMT) uses a visible-light modulated pyramid wavefront sensor (PWFS) to measure the wavefront aberrations, including residual segment piston errors.
