The synthetic catalogue of right ascensions for time service (CTC) was compi- led through the synthesis of time determination data obtained with five photoelectric transits and a visual transit in five observatories or observation stations (Shanghai Observatory, Purple Mountain Observatory, Peking Observatory, Shensi Observatory, and the provisional observation station of Shanghai Observatory in Hainan Island). This catalogue lists 1156 stars with magnitude interval 0.~m1~6.~m6, and declination interval -30°~+66°.In compiling the catalogue, corrections and systematic smooth- ing of the right ascensions of stars were carried out on the basis of FK_4 catalogue, but no corrections of the vernal equinox were made, and no attempt was made to establish our own system of proper motions, therefore CTC is a relative catalogue. Observational data spreading ove, 3-5 years were utilized, the total number of star observations reached 76847, so the catalogue has a rather high precision, especially within the declination zone -5°-+56°, having 1043 stars, the precision of position determination in this zone is in general higher than ±4 ms. In this paper, the method of compiling the CTC catalogue is described, and the precision discussed. As the CTC catalogue has been separately published, in this paper only the right ascensions (1975. 0 equinox) which have been determined by three observatories or stations are given for future reference, together with the epoch of observation, number of observation, total standard error, and internal standard error.

我国综合授时赤经星表(简称CTC),是利用我国五个天文台站(上海天文台,紫金山天文台,北京天文台,陕西天文台以及上海天文台的海南岛临时观测站)的五个光电中星仪和一个目视中星仪测时资料综合而成的.该星表共包括星等范围为0.~m1-6.~m6,赤纬区间为-30°-+66°的1156颗恒星。该星表以FK_4星为基础进行了恒星赤经的个别改正和系统修平,未进行春分点改正和没有建立自己自行系统,因此是一个相对星表.该星表采用了3-5年的观测数据,总观测星次达76847次,从而达到了比较高的精度,尤其是在赤纬带-5°-+56°范围内的1043颗星,其定位精度一般均优于±4ms.在本文中给出了CTC星表的编算方法及其精度.由于CTC星表已专刊发表,本文仅发表CTC星表的三个台站以上观测过恒星的赤经位置(1975.0历元),观测历元,观测次数,赤经位置的总精度σ及内部精度m,以供今后星表工作参考.
