Parkes observations for project PX500 semester 2025APRS_19

This proposal relates to time purchased by the Chinese Academy of Sciences for Parkes follow-up confirmation and timing of FAST discoveries. As the observing time has been purchased this proposal (and the related PX501) does not require TAC grading. The primary reason for submitting a proposal is to ensure an outreach statement and that the proposal is entered into OPAL for the data archive to access. The Chinese team have two time requests. The time scheduled for the first, relating to this proposal, will be allocated in blocks of 24 hours and the data will become available in the data archive with an 18 month embargo period. The second type of time will be scheduled in shorter blocks and the data archived with a 10 year embargo.

本提案涉及中国科学院已为帕克斯射电望远镜（Parkes）的后续验证观测，以及针对500米口径球面射电望远镜（FAST，Five-hundred-meter Aperture Spherical radio Telescope）发现的天文源开展计时观测所购置的观测时长。鉴于该观测时长已完成购置，本提案（及相关的PX501提案）无需通过天文学时间分配委员会（TAC，Time Allocation Committee）的评审定级。提交本提案的核心目的，在于确保纳入科学普及声明，并将本提案录入OPAL系统，以保障数据归档后可被正常访问。中方团队共提出两项观测时长申请：与本提案相关的第一项申请对应的观测时长，将以24小时为分配单元进行调度，相关数据将在18个月的延期公开期后，方可在数据归档系统中获取；第二项观测时长申请将以更短的时段单元进行调度，相关数据将在10年的延期公开期后，方可在归档系统中获取。
