Parkes observations for project P737 semester 2018APRS_13

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.

使用帕克斯射电望远镜（Parkes radio telescope）开展的脉冲星观测，在近年取得了若干极具影响力的天文学研究成果。本观测申请的核心目标，是对无法在常规维护时段内完成测试的新型后端设备开展性能验证。高精度脉冲星计时实验需要对馈源之间的互耦效应进行精准测量，而该项测量仅可通过对PSR J0437-4715进行从升起到落下的全时段观测来实现。我们申请开展此类观测，并将观测结果向该望远镜的所有使用者开放共享。此外，我们还将借助P737开展包括超宽带（UWB）接收机在内的新型接收设备的调试工作。
