TL;DR
The SAGES survey provides high-precision multi-band photometric data for over 48 million sources in the northern sky, enabling detailed studies of stellar parameters and galactic evolution.
Contribution
This paper presents the first data release of SAGES, a new multi-band photometric survey designed to estimate stellar parameters with accuracy comparable to low-resolution spectra.
Findings
Over 48 million sources cataloged with multi-band photometry.
Achieved photometric precision of about 1%.
Astrometric accuracy better than 0.2 arcseconds.
Abstract
The Stellar Abundances and Galactic Evolution Survey (SAGES) of the northern sky is a specifically-designed multi-band 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 and passband produced over 36,092 frames of images in total, covering a sky area of degree. The median survey completeness of all observing fields for the two bands are of mag and mag, respectively, while the limiting magnitudes with signal-to-noise ratio (S/N) of 100 are mag and mag, correspondingly. We combined our catalog with the data release 1 (DR1) of the first of Panoramic Survey Telescope And Rapid Response System (Pan-STARRS1,…
