射电源0716+714和0839+187的光学定位

Optical Positions of Radio Sources IERS 0716+714 and IERS 0839+187

利用北京天文台具有ＣＣＤ终端的６０ｃｍ光学望远镜（Ｖ波段）观测射电源的光学对应体，得到了０７１６＋７１４和０８３９＋１８７精确的光学位置。参考星表采用拉帕尔玛（ＬａＰａｌｍａ）的１８ｃｍ全自动子午环观测资料编制的ＣＡＭＣ星表，该星表是ＦＫ５星表系统。两颗源位置的内符精度约为０．″１９。

With the CCD System attached to the 60 cm optical telescope at Beijing Observatory, the optical positions of radio sources IERS 0716+714 and IERS0839+187 are presented in this paper. The positions in the FK5 system are determined in terms of reference stars from the cataolgue of Carlsberg Automatic Meridian Circle (CAMC). The internal accuracy of the positions is of the order of 0.'19. Our results are also compared with other optical and radio catalogues.
