摘要：

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 mu m maps at high latitudes (\b\ > 30 degrees), 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.
