摘要
Planck 的设计和扫描策略提供了许多冗余级别，可用于内部一致性检验。其中最重要的之一是比较 70GHz 和 100GHz 通道。基于不同的仪器技术，馈源在焦平面上的位置不同，由不同团队使用不同软件独立分析，且靠近弥漫前景发射的最小值，这些通道实际上是两个不同的实验。143GHz 通道在 Planck 上噪声水平最低，且靠近未分辨前景发射的最小值。在本文中，我们分析了 2013 年 Planck 数据所达到的一致性水平。我们集中于 70/100/143GHz 通道图与功率谱之间的比较，特别是在第一和第二声学峰的角尺度上，以及在屏蔽了弥漫银河系发射和强未分辨源的图上。覆盖从 8 度到 15 角分的角尺度的差分图与噪声一致，并且没有显示宇宙微波背景结构的证据。包括针对未分辨源残差的小但重要的修正，我们证明了在 70<l<390 平均的 70 和 100GHz 功率谱之间在 0.8% 水平上的一致，以及相同 l 范围内 143 和 100GHz 功率谱之间 0.4% 的一致。这些数值在 Planck 2013 结果给出的定标总体不确定度之内且与之相符。我们还展示了基于 2013 年似然分析的结果，显示 100/143/217GHz 功率谱之间在 0.35% 的一致性。我们分析了定标程序和波束，以确定这些差异中有多少比例可由已知近似或系统误差解释，这些误差未来甚至能控制得更好，从而进一步减小不确定度。描述了几种可能的小改进...(节略)
