Calibration of Stromgren phot. for late-type stars

The use of model atmospheres for deriving stellar fundamental parameters, such as Teff, log(g), and [Fe/H], will increase as we find and explore extreme stellar populations...随着我们发现并探索极端恒星族群，用于推导有效温度Teff、对数重力log(g)与金属丰度[Fe/H]等恒星基本参数的恒星大气模型（model atmospheres）的应用将日益普及。
