We describe a web-based user interface to retrieve Hyper Suprime-Cam data products, including images and catalogs. Users can access data directly from a graphical user interface or by writing a database SQL query. The system provides raw images, reduced images and stacked images (from multiple individual exposures), with previews available. Catalog queries can be executed in preview or queue mode, allowing for both exploratory and comprehensive investigations. 1. HSC and HSC Survey Hyper Suprime-Cam (HSC) is a new, gigantic camera for the prime focus of Subaru telescope on Mauna Kea, Hawaii. It covers a 1.5 degree diameter field of view with 104 scientific grade Hamamatsu CCDs (Miyazaki 2012). HSC saw first light in January 2013, and is now in the phase of scientific verification. With the combination of wide field coverage (1.77 deg), large aperture (8.2 meter) and excellent image quality of the Subaru telescope, HSC will provide a large, high-quality dataset for various scientific programs. An HSC Collaboration team (consisting of astronomers in Japan, Taiwan and Princeton University) successfully proposed a Strategic Survey Program (SSP) to use 300 nights over 5 years to survey wide (∼ 1500 deg), deep (4 × 7 deg) and ultradeep (2 × 1.77 deg) layers in both broad (grizy) bands and some narrow band filters. The expected data volume is about ∼3 million FITS image data, which corresponds to 300 TB after reduction by our data pipeline. The final catalog is expected to contain ∼1 billion celestial objects, which are multiply measured on each exposure, and a total of ∼6 billion individual detections/measurements. As the output data is so large, it is important to develop an effective data archiving and retrieval system, to accelerate the scientific activities using HSC SSP data. 297
