Parkes observations for project P737 semester 2018APRS_34

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，在近年取得了诸多极具突破性的天文研究成果。本观测提案的核心目标是对新型后端设备开展测试——此类测试无法在常规维护时段内完成。高精度脉冲星计时实验需对馈源（feed）中的串扰（cross-coupling）进行精准测量，而该测量仅可通过对PSR J0437-4715进行从升起到落下的全程观测来实现。我们计划开展此类观测，并将最终观测结果开放给该望远镜的所有使用者。此外，我们还将借助P737对包括超宽带（UWB）在内的新型接收机开展调试工作。
