摘要
利用密云综合孔径射电望远镜，在232MHZ频率，对于北纬30°以上天区的巡天已经完成.除了银道面区域（|b|＜10°）的射电源外，密云总星表（MGC）共包含了26957颗射电源．MGC的完整性和均匀性已在另文讨论．本文将利用所有处理完的MSRT资料和其它已发表的主要射电源表，研究密云总星表的可靠性．
A meter-wave sky survey of the region north of declination +30°has been carried out with the Miyun Synthesis Radio Telescope (MSRT) at 232 MHz. The Miyun Gelleral Catalogue (MGC) colltains 26957 radio sources except those located in the galactic plane, its electronic version is available now. Completeness and uniformity of the MGC has been discussed recently (paper [1]). In this paper, we provide evidence of reliability of the MGC by comparing the MSRT data with other published radio catalogues and also by analyzing the reason why part of the detected sources in the MGC could not be recorded by previous surveys.
