Performance of SAGES DDO51 photometry in separating dwarfs and giants. The sample is using “clean” filtered to exclude galaxies and nonisolated sources. (a) Distribution of sources in the observed (uncorrected for extinction) (GBP − DDO51) versus (GBP − GRP) plane. The color scale represents the logarithmic number density. (b) Variation in the color index (GBP − DDO51) with DDO51 magnitude for stars in the range 1.65 < (GBP − GRP) < 1.75.
