Risk-shared open use (S08B) • Limited number of nights, proposals. • (~ 10 nights, ~ 5 proposals) • Use sidereal natural guide star. • IRCS. (imaging , spectroscopy) • Required functionality • Acquisition Unit (AU) can acquires a sidereal guide star. • AU can shifts the AO point. (dithering) • Wavefront correction in feedback control. • AOIMR can compensate the image rotation. • System startup and shutdown. • Individual check system for each component.
