HSCLA2020 is now live! The release happened in April 2026 and it includes data taken through 2020 processed with hscPipe v8 (which is the same version as used in HSCLA2016). The total area covered in at least one filter is ~7500 square degrees and as many as ~1.5 billion unique sources are detected and measured. The data processed here are from ~1600 hours of observations executed under good conditions. Due to the massive DB, your DB queries may take time. Please be patient!
Welcome! Hyper Suprime-Cam Legacy Archive (HSCLA) is a public archive of processed, science-ready data from HSC taken as part of PI-based programs. There are three versions currently available:
- HSCLA2014 includes data taken in the first year of science operation (i.e., 2014 only).
- HSCLA2016 includes data taken up through 2016.
- HSCLA2020 includes data taken up through 2020 and is the latest release.
This page provides links to the latest release. If you are interested in the previous releases, please go to this page for HSCLA2014 and this page for HSCLA2016.
Note that data from Subaru Strategic Program (SSP) are not included in the HSCLA. The SSP data are served separately from this site. We plan to include the SSP data in the HSCLA once the survey is over and final data release from SSP happens.
We used the same data processing pipelines as HSC-SSP PDRs. Namely, we used hscPipe v.6 used for HSC-SSP PDR2 to process the HSCLA2014 data, and hscPipe v.8 (PDR3) to process HSCLA2016 and 2020. The quality and nature of the processed data are therefore similar (if not identical as there are small differences) to HSC-SSP and we encourage the users to refer to the HSC-SSP data relase website, in particular the known issues and FAQs. A variety of photometric and astrometric QA tests for HSCLA can be found in the AVAILABLE DATA page. Go to DATA ACCESS page for links to our data. Each data retrieval tool comes with its manual, and make sure to refer to it. If you use the HSCLA data in your publications, please acknowledge us! See the ACKNOWLEDGEMENT page for details.
