Parkes observations for project P885 semester 2022OCTS_10

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.我们申请对两颗射电磁星（radio magnetars）维持适度的监测频次，即每10天开展一次观测，以追踪其自转、流量密度与偏振特性。1E 1547.0-5408刚刚在辐射特性与自转两方面均出现了一次“异动”，针对此次事件的短期响应仍不明确。Swift J1818.0-1607仍保持高度活跃状态，其独有的UWL观测能力为探究磁星中迄今仍神秘莫测的射电辐射机制提供了全新的研究契机。我们将以更低的观测频次对XTE J1818-197与刚刚停止辐射的PSR J1622-4950开展观测。本次观测申请的总时长为18小时。
