Spectroscopic analysis of 348 red giants

We present basic atmospheric parameters (Teff, logg, vt, and [Fe/H]) as well as luminosities, masses, radii, and absolute radial velocities for 348 stars, presumably giants,...我们为348颗推测为巨星的恒星提供了基本大气参数（有效温度Teff、表面重力对数logg、微湍流速度vt以及铁丰度[Fe/H]），同时还提供了这些恒星的光度、质量、半径与绝对径向速度……
