我们介绍5321。作为莫哈韦巡天的一部分，用VLBA在15 GHz获得了437个活动星系核（AGN）的质量分辨率总强度和线偏振图，也来自NRAO数据档案。前者是一个长期计划，研究与活动星系核有关的强大秒差距尺度外流的结构和演化。目标活动星系核是从几个通量有限的无线电和。射线样品，并且都具有在15 GHz下大于50 mJy的相关VLBA通量密度。这些活动星系核中大约有80%与。费米LAT仪器探测到的射线源。在1996年1月19日至2016年12月26日期间，绝大多数VLBA观测到5-15次，间隔时间从一个月到几年不等，最典型的采样间隔为六个月。对这些活动星系核喷流的线偏振和圆偏振演化的详细分析将在本系列的其他论文中介绍。
We present 5321. mas-resolution total intensity and linear polarization maps of 437 active galactic nuclei (AGNs) obtained with the VLBA at 15 GHz as part of the MOJAVE survey, and also from the NRAO data archive. The former is a long-term program to study the structure and evolution of powerful parsec-scale outflows associated with AGNs. The targeted AGNs are drawn from several flux-limited radio and.-ray samples, and all have correlated VLBA flux densities greater than similar to 50 mJy at 15 GHz. Approximately 80% of these AGNs are associated with.-ray sources detected by the Fermi LAT instrument. The vast majority were observed with the VLBA on 5-15 occasions between 1996 January 19 and 2016 December 26, at intervals ranging from a month to several years, with the most typical sampling interval being six months. A detailed analysis of the linear and circular polarization evolutions of these AGN jets is presented in the other papers in this series.
