Parkes observations for project P885 semester 2022OCTS_11

We request a continued modest monitoring cadence of once every 10 days for two radio magnetars, to track their rotation, flux density, and polarisation. 1E 1547.0-5408 has just suffered a 'hiccup' in radiative properties as well as in its rotation, and the near-term response to this event remains unclear. Swift J1818.0-1607 remains quite dynamic, and the unique UWL capabilities promise new opportunities to probe still mysterious radio emission mechanisms in magnetars. We will observe XTE J1810-197 and PSR J1622-4950, which has just ceased emission, less frequently. The overall request is 18 hours.

我们请求对两颗射电磁星（radio magnetar）维持适度的监测频次，即每10天一次，以追踪它们的自转、流量密度以及偏振特性。1E 1547.0-5408的辐射特性与自转状态刚刚出现了一次“异动”，目前对该事件的短期响应机制仍不明确。Swift J1818.0-1607仍处于高度活跃状态，其独特的UWL（UWL）观测能力为探究磁星中仍未明晰的射电辐射机制提供了新的契机。对于刚刚停止辐射的XTE J1810-197与PSR J1622-4950，我们将降低其监测频次。本次整体观测时长需求为18小时。
