Abstract: Ghosts, the scattered lights of bright objects, are investigated for the Subaru Prime Focus Camera (Suprime-Cam). We focused on “circular ghosts” around bright stars in this work. We identified the reflecting surfaces, derived empirical relations about the shape and the position, and implemented software to fit and subtract them automatically. Still more improvement is required for spider and PFU shadow correction.
