| Abstract: | In this paper,caused by the systematic difference FK5-FK4,the change of nutation model and of aberration constant, three kinds of corrections for the influence on pole coordinates of JYD_(1968.0) pole coordinate system are studied. The results of the JYD_(1968.0) system including these changes are compared with the BIH system.The correction on the pole coordinates of JYD_(1968.0) caused by the systematic difference of FK5-FK4 from 1962 to 1986 is given in Fig. 1. The correction for the change of the nutation model from 1962 to 1986 is shown in Fig. 2. And in Fig. 3 the correction for the change of aberration constant from 1962 to 1967 is given. |
