-For these power spectra I degraded the FSL map to nside=64 (roughly 1 deg pixels), multiplied by alpha, and added white noise where each map pixel value is drawn from a gaussian with sigma equal to the quoted noise level. The power spectra are calculated using the healpy anafast function.
+For these power spectra I multiplied by the FSL map by alpha, added white noise where each map pixel value is drawn from a gaussian with sigma equal to the quoted noise level (scaled to appropriate pixel size, nside=512), and applied the galaxy mask. The power spectra are calculated using the healpy anafast function.
 **Bottom line:**  We need to remove about 60% of the sidelobes to get to r of 10^-3 and about 90% to reach r = 10^-4
