Parkes observations for project P737 semester 2018APRS_41

Pulsar observations using the Parkes radio telescope have led to some of the most exciting astronomical results in the last few years. The aim of this proposal is to carry out tests of the new backend instruments which cannot be carried out during standard maintenance periods. High precision pulsar timing experiments require cross-coupling in the feed to be measured. This can only be done using observations of PSR J0437-4715 from rise-to-set. We propose to undertake such observations and make the results available for any users of the telescope. We will also use P737 to commission new receivers such as the UWB.

使用帕克斯（Parkes）射电望远镜开展的脉冲星观测，近数年来取得了多项振奋人心的重要天文学研究成果。本观测提案旨在对新型后端仪器开展测试，此类测试无法在常规维护周期内进行。高精度脉冲星计时实验要求对馈源间的互耦效应进行测量，而该测量仅可通过对脉冲星PSR J0437-4715进行从升起到落下的全时段观测来完成。我们提议开展此类观测，并将观测结果向该望远镜的全体使用者公开。此外，我们还将依托P737项目开展超宽带（UWB）等新型接收机的调试工作。
