| 英文摘要 | The Stellar Abundances and Galactic Evolution Survey (SAGES) of the northern sky is a specifically designed multiband photometric survey aiming to provide reliable stellar parameters with accuracy comparable to those from low-resolution optical spectra. It was carried out with the 2.3 m Bok telescope of Steward Observatory and three other telescopes. The observations in the u ( s ) and v ( s ) passband produced over 36,092 frames of images in total, covering a sky area of & SIM;9960 deg(2). The median survey completenesses of all observing fields for the two bands are u (s) = 20.4 mag and v ( s ) = 20.3 mag, respectively, while the limiting magnitudes with signal-to-noise ratio of 100 are u ( s ) & SIM; 17 mag and v ( s ) & SIM; 18 mag, correspondingly. We combined our catalog with the data release 1 (DR1) of the first Panoramic Survey Telescope And Rapid Response System (Pan-STARRS, PS1) catalog, and obtained a total of 48,553,987 sources that have at least one photometric measurement in each of the SAGES u ( s ) and v ( s ) and PS1 grizy passbands. This is the DR1 of SAGES, released in this paper. We compared our gri point-source photometry with those of PS1 and found an rms scatter of & SIM;2% difference between PS1 and SAGES for the same band. We estimated an internal photometric precision of SAGES to be of the order of & SIM;1%. Astrometric precision is better than 0.& DPRIME;2 based on comparison with DR1 of the Gaia mission. In this paper, we also describe the final end-user database, and provide some science applications. |
