我们将19 GHz全天空宇宙微波背景调查与其他地图交叉关联，以量化前景的贡献。在高纬度（|b| > 30°），用dibe 240、140和100 μm图检测到相关性，用Haslam 408 MHz和Reich & Reich 1420 MHz同步加速器图检测到边际相关性。前者与COBE差分微波辐射计和萨斯卡通实验探测到的高频外推结果一致，与自由-自由和旋转尘埃颗粒发射一致。
We cross-correlate a 19 GHz full sky cosmic microwave background survey with other maps to quantify the foreground contribution. Correlations are detected with the DIRBE 240, 140, and 100 μm maps at high latitudes (|b| > 30°), and marginal correlations are detected with the Haslam 408 MHz and the Reich & Reich 1420 MHz synchrotron maps. The former agree well with extrapolations from higher frequencies probed by the COBE Differential Microwave Radiometer and Saskatoon experiments and are consistent with both free-free and rotating dust grain emission.
