摘要
给出了鬼星团天区中部560颗恒星的高精度位置，这些位直属于FKS系统，相对于J2000．0的赤道和春分点，平均观测历元为J1986.17左右，每个坐标方向的标准误差为±10～50mas。
High - precision positions of 560 stars in the central part of the Praesepe region are giv en, which based on the FK5 system and related to the J2OOO. 0 equator and equinox, with themean observational epoch being about J1986. 17 and the standard errors in each direction±10～50 mas.
