Metallicity Mapping with <i>gri</i> Photometry: The Virgo Overdensity and the Halos of the Galaxy
We describe the methodology required for estimation of photometric estimates of metallicity based on the SDSS gri passbands, which can be used to probe the properties of main-sequence stars beyond ~ 10 kpc, complementing studies of nearby stars from more metallicity-sensitive color indices that involve the u passband. As a …
