我们报告了6dFGS基本平面（6dFGSv）目录，该目录用于估计本地（z < 0.055）宇宙中近9000个早期型星系的距离和特殊速度。对11 315个星系样本的6dF v波段光谱进行了速度色散的互相关推导，典型信噪比为12.9 A^(−1)；中间速度色散为163 km s^(−1)，中间测量误差为12.9%。光度基本面（FP）参数（有效半径和表面亮度）由JHK 2MASS对11102个星系的图像确定。独立的J波段和k波段测量结果的比较表明，进入FP的组合光度参数X_（FP）的平均不确定度为每波段0.013指数（3%）。通过形态学的视觉分类，选取了近9000个形成6dFGSv的早期型星系样本。该目录已被用于研究恒星群对星系尺度关系的影响，研究FP随环境和星系形态的变化，探索通过、沿着和跨越FP的恒星群的趋势，以及绘制和分析局部特殊速度场。
We report the 6dFGS Fundamental Plane (6dFGSv) catalogue that is used to estimate distances and peculiar velocities for nearly 9000 early-type galaxies in the local (z < 0.055) universe. Velocity dispersions are derived by cross-correlation from 6dF V-band spectra with typical S/N of 12.9 A^(−1) for a sample of 11 315 galaxies; the median velocity dispersion is 163 km s^(−1) and the median measurement error is 12.9 per cent. The photometric Fundamental Plane (FP) parameters (effective radii and surface brightnesses) are determined from the JHK 2MASS images for 11 102 galaxies. Comparison of the independent J- and K-band measurements implies that the average uncertainty in X_(FP), the combined photometric parameter that enters the FP, is 0.013 dex (3 per cent) for each band. Visual classification of morphologies was used to select a sample of nearly 9000 early-type galaxies that form 6dFGSv. This catalogue has been used to study the effects of stellar populations on galaxy scaling relations, to investigate the variation of the FP with environment and galaxy morphology, to explore trends in stellar populations through, along and across the FP, and to map and analyse the local peculiar velocity field.
