+          This is the normalized value of sigmaXY, i.e. sigmaXY/(sigmaX * sigmaY). This is
+          often called the correlation coefficient, r. It is zero if the X and Y profiles
+          are not correlated, meaning that the distribution is not tilted with respect to
+          the X and Y axes.</td>
