摘要
本文给出了由 ESA Planck 任务在 30 至 857 GHz 之间观测到的 Planck 非热（即同步辐射主导）辐射源多频星表（PCNT）。该星表通过筛选在全任务全天温度图中 30 和 143 GHz 处被探测到的目标而构建，要求在使用特定墨西哥帽小波滤波后两通道中至少之一信噪比（S/N）>3。结果选出了 29400 个源候选体。随后，在这些目标位置使用矩阵滤波方法进行了多频分析，并在 Planck 的九个通道中计算了所有源的磁通密度与误差。本星表是首个在毫米和亚毫米波长发表的无偏全天同步辐射主导源星表，并构成了对非热河外源（其辐射由中心活动星系核主导）进行统计研究的强大数据库。除完整多频星表外，我们还定义了亮源 Planck 非热辐射源多频星表 PCNTb，其中仅筛选在 30 和 143 GHz 处 S/N>4 的目标。该星表在采用的 Planck GAL070 掩膜之外探测到 1146 个致密源；因此，这些源构成了高可靠性的河外射电源样本。我们还标记了高显著子样本 PCNThs，其为在全部九个 Planck 通道中 S/N>4 探测到的 151 个源的子集，其中 75 个位于此处采用的 Planck 掩膜之外。位于银河系掩膜内的其余 76 个源极可能是银河系天体。
