Data Release

lastest DR1 (Jan. 2017)

DR2 due in Dec. 2017

The Beijing-Arizona Sky Survey (BASS) is an ambitious wide-field multicolor survey of 5000 deg2 of the Northern Galactic Cap using the 90prime imager on the 2.3m Bok Telescope at Kitt Peak, as a three to four-year collaboration between the Chinese team led by NAOC and the US team led by Steward Observatory, University of Arizona. The survey will use 240 nights, covering SDSS g and r bands, reaching limiting AB magnitude of 24.0 and 23.6 (5σ), respectively. The survey will follow the successful SCUSS mode with strong participations and support from both China and US teams and produce high level science products for the general astronomical community. The survey data will allow effective target selection for the DESI dark energy spectroscopic survey project in the survey area. There are three image surveys that consititues the DESI imaging legacy surveys, which are mainly used for DESI spectroscopic targeting: the BASS, Mayall z-band Legacy Survey (MzLS), and the DECam Legacy Survey (DECaLS). The BASS and MzLS cover the same area of about 5500 deg² in the north Galactic cap, while the DECaLS cover an area of about 9000 deg² along the equator in both south and north. The DESI team will also reduce the data from all three surveys. The latest data release (DR4) include the BASS and MzLS data taken before 2016 July.

Acknowledgement

Whatever level of the BASS data you used, we hope you add the following acknowledgement in your paper.

BASS is a collaborative program between the National Astronomical Observatories of theChinese Academy of Science and Steward Observatory of the University of Arizona. It is a key project of the Telescope Access Program (TAP), which has been funded by the National Astronomical Observatories of China, the Chinese Academy of Sciences (the Strategic Priority Research Program “The Emergence of Cosmological Structures” grant no. XDB09000000), and the Special Fund for Astronomy from the Ministry of Finance. BASS is also supported by the External Cooperation Program of the Chinese Academy of Sciences (grant no. 114A11KYSB20160057) and the Chinese National Natural Science Foundation (grant no. 11433005). The BASS data release is based on the Chinese Virtual Observatory (China-VO).
