Parkes observations for project P737 semester 2018APRS_44

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.

利用帕克斯射电望远镜（Parkes radio telescope）开展的脉冲星观测，近年来取得了多项备受瞩目的天文学研究成果。本提案旨在针对新型后端设备（backend instruments）开展无法在常规维护时段内完成的测试工作。高精度脉冲星计时实验需要对馈源串扰（cross-coupling in the feed）进行测量，而该测量仅可通过对脉冲星PSR J0437-4715开展从升起到落下的连续观测来实现。我们提议开展此类观测，并将观测结果向该望远镜的所有使用者开放。此外，我们还将借助P737对包括超宽带（UWB）接收机在内的新型接收机进行调试。
