In Cols.~5$-$8 are the sigmas of the Gaussians that best fit the bMS and rMS~color distributions, with errors. In the next two columns are the \nbr~ratio and its error. The next-to-last column gives the color difference between the two Gaussian peaks, and the final column identifies the color baseline of the data~set. \end{table}
