Parkes observations for project PX500 semester 2025APRS_12

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）望远镜对500米口径球面射电望远镜（Five-hundred-meter Aperture Spherical radio Telescope, FAST）发现源的跟进验证与计时观测所购置的观测时长。鉴于观测时长已完成购置，本提案（及相关提案PX501）无需接受时间分配委员会（Time Allocation Committee, TAC）的评审定级。提交本提案的核心目的，是确保纳入科普宣传说明，并将本提案录入OPAL系统，以供数据存档调用。中国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，观测时长将以24小时为分配单元，所产生的数据将在数据存档库中保留18个月的保密期后方可对外公开；第二项申请的观测时长将以更短的单元进行分配，对应数据的存档保密期为10年。
