Other Abstract根据原中国科学院陕西天文台(CSAO)(现已更名为中国科学院国家授时中心)与俄罗斯东西伯利亚物理技术和无线电测量研究所(VS NIIFTRI)之间签定的科学合作协议,陕西天文台光电等高仪1型在伊尔库茨克进行了为期近5年的星表观测.根据这些高精度的观测资料共编算出包括817颗星的无赤纬盲区的等高仪星表(其中首批200颗已在欧洲上发表)和22颗射电星的光学位置表,后者在本文中给出.此外,这几年的测时测纬资料还同时发往莫斯科,参加俄罗斯的地球定向参数(EOP-earth orientation parameters)服务系统.The observation of star position for catalogue compiling had been made in Irkutsk for 5 years with the Chinese photoelectric astrolabe Mark-1 according to the agreement of scientific cooperation between CSAO and VS NIITRI. This cooperation has taken the advantage of com-bination of the large zenith distance (45degrees) of almucantar for the astrolabe Mark-1 with the high latitude(52degrees)for Irkutsk, which could eliminate the blind zone existing in declination measure-ments for all the astrolabe catalogues. Based on the cooperation,a star catalogue containing posi-tions of 817 stars had been completed;besides, the positions of 22 radio stars had been measured precisely in both right ascension and declination, which are given in this paper.
