给出了1995 - 1999年木星冲日期间8颗不规则木星卫星的天体测量位置。这些位置进行了测量，在1.6米的反射器的卡塞格伦焦点获得的204 CCD帧。它们与JPL Development Ephemeris的理论计算位置进行了比较。八颗卫星的所有观测值的观测值减去计算的标准差为σα = 0。�� 071和σ δ = 0。�� 052.利用USNO-A2.0星表进行天体测量定标。
The astrometric positions of eight irregular Jovian satellites are given for the oppositions of the planet from 1995 to 1999. These positions were measured on 204 CCD frames obtained at the Cassegrain focus of a 1.6 m reflector. They are compared with the theoretically calculated positions from JPL Development Ephemeris. The observed minus-calculated standard deviation for all observations of the eight satellites are σα = 0. �� 071 and σ δ = 0. �� 052. The USNO-A2.0 catalog was used for the astrometric calibration.
