The Stellar Abundances and Galactic Evolution Survey (SAGES) V: The First Data Release of DDO51 Band
Qiqian Zhang ; Zhou Fan ; Gang Zhao
This dataset is based on DDO51-band observations obtained with the Nanshan One-meter Wide-field Telescope (NOWT, f/2.2, 1.3°×1.3° FOV) between September 2023 and January 2024, covering ~2,500 deg² of the northern sky. The final merged catalog contains 10,489,790 sources with calibrated DDO51 magnitudes, photometric uncertainties, astrometric positions (ICRS, J2023.8), Gaia DR3 cross-match identifiers, quality bitmask flags (FLAGS_SAGES), variability flags, galaxy contamination flags, and multi-scale blending diagnostics. For further details, please refer to our paper.
