Abstract
This paper presents the second data release of the Hyper Suprime-Cam Subaru Strategic Program, a wide-field optical imaging survey using the 8.2 m Subaru Telescope. The release includes data from 174 nights of observation through 2018 January. The Wide layer data cover about 300 deg2 in all five broad-band filters (grizy) to the nominal survey exposure (10 min in gr and 20 min in izy). Partially observed areas are also included in the release; about 1100 deg2 is observed in at least one filter and one exposure. The median seeing in the i-band is 0.''6, demonstrating the superb image quality of the survey. The Deep (26 deg2) and UltraDeep (4 deg2) data are jointly processed and the UltraDeep-COSMOS field reaches an unprecedented depth of i ∼ 28 at 5 σ for point sources. In addition to the broad-band data, narrow-band data are also available in the Deep and UltraDeep fields. This release includes a major update to the processing pipeline, including improved sky subtraction, PSF modeling, object detection, and artifact rejection. The overall data quality has been improved, but this release is not without problems; there is a persistent deblender problem as well as new issues with masks around bright stars. The user is encouraged to review the issue list before utilizing the data for scientific explorations. All the image products as well as catalog products are available for download. The catalogs are also loaded into a database, which provides an easy interface for users to retrieve data for objects of interest. In addition to these main data products, detailed galaxy shape measurements withheld from Public Data Release 1 (PDR1) are now available to the community. The shape catalog is drawn from the S16A internal release, which has a larger area than PDR1 (160 deg2). All products are available at the data release site, https://hsc-release.mtk.nao.ac.jp/.
