Abstract

We present the results of a large-scale 5-GHz Very Large Array (VLA) survey of the northern sky searching for sources that exhibit intraday variability (IDV). The observations were made over four epochs, each of 3 days in January, May and September 2002 and January 2003. The objective is to obtain a large sample of IDV sources in order to derive reliable statistics of the microarcsecond properties of the source population and the scattering properties of the interstellar medium.

北方天空的微弧秒闪烁诱发变率(MASIV)测量

我们介绍了一项大规模的5 ghz甚大阵列(VLA)对北方天空的调查结果，该调查旨在寻找表现出日变率(IDV)的源。在2002年1月、5月、9月和2003年1月进行了4个时期的观测，每个时期3天。目的是获得大量IDV源样本，以便获得可靠的统计数据，了解源群的微弧秒特性和星际介质的散射特性。
