Public Data Release 3
Welcome to the Hyper Suprime-Cam Subaru Strategic Program Data Release Site!
The third public release of HSC-SSP occurred on 31 August 2021. The release includes over 600 square degrees of deep multi-color data served through dedicated databases and user interfaces. The figures below show the area covered in this release and the table gives an overview of the data in the three survey layers, Wide, Deep, and UltraDeep. Refer to our survey website for details of the survey design. Also, read the data release paper for details of this release.
NEW: HSC Legacy Archive 2016
This side offers processed data from HSC-SSP, a large observing program conducted at the Subaru Telescope. While 1/3 of the observing time was used for SSP, the reminder has been used for PI programs. The observatory processed public raw data from PI programs conducted through 2016 and the science-ready data is available at the HSC Legacy Archive (HSCLA). Check out the website here.
Here is a list of technical papers for your reference. Please reference relevant papers in your publication. PASJ special issue for HSC-SSP has been published and many of the papers here are included in that issue.
IMPORTANT: HSC source names
A potential confusion with sources from the Hubble Source Catalog (which is also HSC) was pointed out by the IAU Working Group Designations. Please name sources from the Hyper Suprime-Cam Survey as ‘HSC Jhhmmss.ss+/-ddmmss.s’.
Hyper Suprime-Cam Legacy Archive
This site serves processed data from the HSC-SSP. There are a lot of data taken as part of PI programs (2/3 of the HSC observing time is for PI programs). We have processed data from these PI programs and make the science-ready data available at the Hyper Suprime-Cam Legacy Archive. Data from 2014 are available at this point, but we are processing more data and hope to release data taken through 2016 in later this year.
The Collaboration and Supporting Agencies
The Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) is led by the astronomical communities of Japan and Taiwan, and Princeton University. The instrumentation and software were developed by the National Astronomical Observatory of Japan (NAOJ), the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU), the University of Tokyo, the High Energy Accelerator Research Organization (KEK), the Academia Sinica Institute for Astronomy and Astrophysics in Taiwan (ASIAA), and Princeton University. The survey was made possible by funding contributed by the Ministry of Education, Culture, Sports, Science and Technology (MEXT), the Japan Society for the Promotion of Science (JSPS), (Japan Science and Technology Agency (JST), the Toray Science Foundation, NAOJ, Kavli IPMU, KEK, ASIAA, and Princeton University.
