Using the Saskatoon data, we estimate the power averaged through a set of ten filters designed to make the errors on the power estimates uncorrelated. We also present an improvement to using the window function, $W_l$, for calculating bandpower estimates.3 pages, LaTeX, 2 included eps figures, uses sprocl.styAstrophysicstext
