Cepheid radial velocities

A catalog of Cepheid variables is used to probe the kinematics of the Galactic disk. Radial velocities are measured for eight distant Cepheids toward l=300{deg}; these new...本数据集为造父变星（Cepheid variables）星表，用于探究银盘（Galactic disk）的运动学特性。研究为8颗朝向银经300°的遥远造父变星测定了视向速度（radial velocities），这些新的……
