abstract = "ULTIMATE-Subaru is the next generation wide-field near-infrared instrument for the Subaru Telescope, assisted by Ground-Layer Adaptive Optics (GLAO). The GLAO system is required to provide ∼0.2 arcsec image quality in FWHM at K band (2.2 µm) uniformly over 14×14 arcmin2 field of view, with more than 90 \% sky-coverage. In previous studies of the GLAO system, we assumed the use of global shutter readout for the WFS detector. However, the current design of the GLAO WFS system uses the CMOS cameras employing rolling shutter readout. We have implemented the rolling shutter readout in the end-to-end numerical simulation according to the current design of the GLAO WFS system and update the GLAO performance evaluation. We also evaluate the temporal error with lower frame rate of the NGS WFS that is required to keep the GLAO performance with faint NGSs.",
