摘要
本文刻画了 Planck HFI 探测器的有效波束、有效波束窗函数及其相关误差。有效波束是包含光学、探测器、数据处理和扫描策略效应的角响应。窗函数是该波束在谐波域的表示，用于恢复无偏的 CMB 角功率谱测量。HFI 是一种扫描仪器，其有效波束是以下因素的卷积：(a) 望远镜和馈源的光学响应；(b) 时序数据的处理以及测辐射热计和电子时间响应的反卷积；(c) 合并多次巡天以生成地图。时间响应函数是利用对木星和土星的观测并通过最小化巡天差异残差来测量的。扫描波束是仪器反卷积后的角响应，并利用对火星的观测进行刻画。每个 HFI 频段的主波束立体角确定精度优于 0.5%。对木星和土星的观测将近旁瓣（5 度以内）限制在总立体角的约 0.1%。时间响应残差在扫描波束中表现为长拖尾，但贡献小于总量的 0.1%。波束产品的偏差和不确定性是通过使用包含仪器噪声和已知系统效应影响的模拟行星观测系综来估计的。这些系综的相关结构由五个误差本征模很好地描述，它们在谐波域中次于样本方差和仪器噪声。一系列一致性检验提供了信心，表明误差模型充分描述了数据。有效波束窗函数的总误差在 100GHz 高达 时低于 1%，在 143 和 217GHz 高达 时低于 0.5%。
