External photometric validation of the SAGES DDO51 calibration. Symbols and color coding follow those in Figure 12. The panels show the magnitude residuals (Δm = DDO51SAGES − mref) as a function of Gaia G magnitude for a crossmatched sample of high-quality point sources. (a) Comparison with synthetic DDO51 magnitudes from Gaia XP spectra. (b) Comparison with J-PLUS J0515 photometry.
