Parkes observations for project PX500 semester 2025APRS_18

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为帕克斯（Parkes）望远镜开展后续验证观测，以及对FAST（500米口径球面射电望远镜）发现天体进行计时观测所获批的观测时长。鉴于本提案（及相关联的PX501提案）已获得观测时长配额，因此无需通过天文时间分配委员会（Time Allocation Committee, TAC）的评审分级。提交本提案的核心目的，在于确保包含科普宣传声明，并将本提案录入OPAL系统以支持数据存档与后续访问。中方团队共提出两项观测时长申请：其一对应本提案的观测时长，将以24小时为单元进行批次分配，相关数据将在数据存档库中保留18个月的禁运期；其二的观测时长将以更短的单元进行批次分配，对应数据存档后将保留10年的禁运期。
