Parkes observations for project PX500 semester 2025APRS_17

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.本提案关联中国科学院为帕克斯（Parkes）望远镜开展后续验证观测，以及针对500米口径球面射电望远镜（Five-hundred-meter Aperture Spherical radio Telescope，FAST）发现的天体进行计时观测所获批的观测时长。鉴于本提案（及相关提案PX501）所涉观测时长已获批，因此无需经过时间分配委员会（Time Allocation Committee，TAC）的评审定级。提交本提案的核心目的有二：一是确保纳入科普声明内容，二是将本提案录入OPAL系统，以便数据归档后可被检索调用。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所涉观测时长，将以24小时为单元进行分配，相关数据归档后将设置18个月的公开封禁期；第二项申请的观测时长将以更短的时段单元进行排程，相关数据归档后将设置10年的公开封禁期。
