CMB Temperature Polarization Correlation and Primordial Gravitational Waves: WMAP5

Figure 4

The upper left plot shows the results for the Wilcoxon rank sum test using the unbinned data. The dashed red line shows the mean value of 𝑈 if 𝑟=0. The solid black line is the distribution of 𝑈 with the WMAP5 dataset and a mock dataset with WMAP5 error bars and 𝑟=0. The upper right plot is the same as the upper left plot except it uses the binned data. The lower left plot shows the results for the 𝑆/𝑁 test using the unbinned data. The dashed red line is the value of 𝑆/𝑁 for WMAP5. The solid black line is the distribution of the 𝑆/𝑁 value for a mock dataset with 𝑟=0 and WMAP5 error bars. The lower right plot is the same as the lower left plot except it uses the binned data.
