我们提出了三个地图的毫米波天空创建相结合的数据从南极望远镜（SPT）和普朗克卫星。我们使用的数据从SPT-SZ调查，调查2540 deg 2的天空与弧分分辨率在三个频段集中在95，150，和220 GHz，和全任务普朗克温度数据在100，143，和217 GHz频段。SPT-SZ和普朗克数据的线性组合在球谐空间中计算，权重来自两种仪器的噪声。这种加权方案导致普朗克数据在组合地图中提供大部分的大角度尺度信息，而较小尺度的信息来自SPT-SZ数据。在地图上进行了一些测试。我们发现它们的角功率谱与理论预测的谱和以前发表的结果非常吻合。
We present three maps of the millimeter-wave sky created by combining data from the South Pole Telescope (SPT) and the Planck satellite. We use data from the SPT-SZ survey, a survey of 2540 deg2 of the the sky with arcminute resolution in three bands centered at 95, 150, and 220 GHz, and the full-mission Planck temperature data in the 100, 143, and 217 GHz bands. A linear combination of the SPT-SZ and Planck data is computed in spherical harmonic space, with weights derived from the noise of both instruments. This weighting scheme results in Planck data providing most of the large-angular-scale information in the combined maps, with the smaller-scale information coming from SPT-SZ data. A number of tests have been done on the maps. We find their angular power spectra to agree very well with theoretically predicted spectra and previously published results.
