摘要：

我们描述了一个4.85 GHz的调查明亮，平谱无线电源进行的Effelsberg 100米望远镜，试图提高现有的调查，如CRATES的完整性。我们报告的结果，这些观测和后续的8.4 GHz的观测与VLA的一个子集的样品。我们评论连接到WMAP点源目录和调查的有效性补充CRATES天空覆盖。

英文摘要：

We describe a 4.85 GHz survey of bright, flat-spectrum radio sources conducted with the Effelsberg 100 m telescope in an attempt to improve the completeness of existing surveys, such as CRATES. We report the results of these observations and of follow-up 8.4 GHz observations with the VLA of a subset of the sample. We comment on the connection to the WMAP point source catalog and on the survey's effectiveness at supplementing the CRATES sky coverage.
