Optical positions of 85 radio stars and 3 radio sources relative to the AGK3 and SAO have been determined using the 40 cm astrograph of Zo-se. The mean precision is 0.13″ in right ascension and 0.11″ in declination. Comparisons with the other cat

In this paper the corrections of positions and proper motions (J2000) of FK4 were obtained. For different kinds of observational methods the formulae of calculating the influence of systematic differences of FK4 on time and latitude determinations we

We have measured an optical position of 3C 273 in the AGK3 system using the 40cm astrograph of Shanghai Observatory. Combining with others' observations, we have derived a “proper motion”. A comparison with other results is made.
