We performed a simple phenomenological fit with a power-law model in the 1-5 keV band, where the background is nearly negligible. We used XSPEC version 12.14.1 (K. A. Arnaud 1996) for the spectroscopy. The derived flux in the 2-10 keV band and power-law index are ∼1.5×10 −14 erg s −1 cm−2 and∼2.6 for CXOU J1912

While the present work focuses on the data release and calibration of the DDO51 band, these results illustrate the expected role of DDO51 as the primary gravity-sensitive component of the SAGES system. The primary science drivers for the SAGES DDO51 observations include: (1) photometric pre-selection of giant stars for spectroscopic follow-up surveys; (2) large-
