中文摘要
调试成像和波束形成数据通用的通量校准刻度。寻找持续的,非脉冲发射的系统,可能导致内部的二元冲击。描述低频日食的特征,并将其与高频观测进行比较,以了解负责的物理机制。确定整个轨道上自由电子的柱密度的变化,以便从伴星中推断出质量损失率。测量来自法拉第旋转的微分磁场,以确定伴星的食区和附近的磁场。获取长期监测轨道变化的定时数据。
英文摘要
Commission a flux calibration scale common to the imaging and beamformed data. Look for persistent, unpulsed emission from the system that could result from the intra-binary shock. Characterise the eclipses at low frequency and compare them with higher frequency observations in order to understand the physical mechanism that is responsible. Determine the variation in column density of free electrons throughout the orbit in order to infer a mass loss rate from the companions. Measure the differential magnetic field from the Faraday rotation in order to determine the magnetic field in the eclipsing region and vicinity of the companion. Obtain timing data for the long-term monitoring of the orbital variability.
