Abstract

Prime Focus Spectrograph is a next-generation spectroscopic instrument being installed on Subaru Telescope. The key to the success of its cosmological survey is accurate sky subtraction to extract galaxy emission lines from very bright night-sky emissions. We model the two-dimensional point spread function considering various e↵ects such as optical aberrations in the spectrographs and vignetting on the telescope prime focal plane. We are developing models using commissioning data, and currently we have achieved 1 % precision in one-dimensional spectra for the aberration model.
