| Abstract | |
Prime Focus Spectrograph (PFS) is a next generation instrument mounted on the Subaru telescope. It is a fiberfed multiplex system covering a wide field of view (1.3 degree in diameter), which enables to acquire approximately 2400 spectra of science objects simultaneously. In order to efficiently use fibers, open-use programs will share fibers with each other (the fiber-sharing mode). Here, we introduce the PFS Pointing Planner (PPP), the tool to optimize the pointing centers. Its goal is to efficiently observe all allocated time of science programs while assigning as many fibers as possible to science targets on each pointing. The tool incorporates a flexible weight scheme which considers factors such as the science priority, surface density and exposure time. We present the simulation results of PPP with mock science programs, and discuss its performance in diverse science cases. (AU) | |
