Description

In this study, we present stellar parameters, including effective temperature (Teff), metallicities (FeH), absolute magnitudes (M_{G}), distances (d), and reddening values (E_{G_{BP},G_{RP}}), for a sample of 141 million stars from the SkyMapper Southern Survey (SMSS) using the SPar algorithm. This algorithm employs a fitting procedure to match the multi-band stellar photometries and derive the stellar parameters (Teff, FeH, M_G, d and E_{G_{BP},G_{RP}}) on an individual star basis, following the approach outlined in our previous work. By extending our investigation to include stars in both high and low Galactic latitudes, this study successfully corrects for extinction in stars located in low Galactic latitudes, enabling precise determination of their stellar parameters.
