Parkes observations for project PX500 semester 2025APRS_08

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开展帕克斯（Parkes）射电望远镜后续验证观测，以及针对500米口径球面射电望远镜（FAST）发现源的计时观测所申请的观测时长。鉴于该观测时长已完成采购，本提案（及相关提案PX501）无需经过时间分配委员会（TAC）的评审分级。
提交本提案的核心目的，在于确保纳入科普宣传说明，并将本提案录入OPAL系统，以便数据档案库可调取相关数据。
中方团队共提出两项观测时长申请。与本提案对应的第一项申请，其观测时长将以24小时为单位进行批次分配，相关数据将在数据档案库设置18个月的保密期后对外开放。
第二项申请对应的观测时长将以更短的批次进行分配，相关数据将在设置10年保密期后存入档案库。
