PFS (Prime Focus Spectrograph), a next generation facility instrument on the 8.2-meter Subaru Telescope, is a very wide-field, massively multiplexed, optical and near-infrared spectrograph. Exploiting the Subaru prime focus, 2394 reconfigurable fibers will be distributed over the 1.3 deg field of view. The spectrograph has been designed with 3 arms of blue, red, and near-infrared cameras to simultaneously observe spectra from 380nm to 1260nm in one exposure at a resolution of ~ 1.6-2.7Å. An international collaboration is developing this instrument under the initiative of Kavli IPMU. The project recently started undertaking the commissioning process of a subsystem at the Subaru Telescope side, with the integration and test processes of the other subsystems ongoing in parallel. We are aiming to start engineering night-sky operations in 2019, and observations for scientific use in 2021. This article gives an overview of the instrument, current project status and future paths forward.
Hyper Suprime-Cam (HSC) is the optical and near-infrared wide-field camera equipped on the Subaru Telescope. Its huge field of view (1.5 degree diameter) with 104 CCDs and the large mirror (8.2m) of the telescope will make us to study the Universe more efficiently. The analysis pipeline for HSC data produces processed images, and object catalogs of each CCD and stacked images. For survey in next 5 years, the number of rows in the object catalog table will reach to at least 5 x 109. We show the outline of the database systems of HSC data to store those huge data.
We describe a data providing system for Hyper Suprime-Cam (HSC) of Subaru Telescope. The data providing system provides HSC data including images and catalogs of celestial objects derived from them to individual co-investigators of the Subaru Strategic Survey Program with HSC through a website. Users can select the data that they need by using its graphical user interface or writing a query in SQL and download the selected images or the catalogs.
