 The plots below show the spectra taken from the old nside=512 maps at left, and the new nside=2048 maps at right.
+I think these look sensible - noise and llcdm extend out to 2*nside as before.
+The PySM foreground model contains high ell fill in out to 3*512 so foreground goes to zero above ell=1536.
+Also note that there is no lensing scale down in the new nside=2048 maps - A_L=1.
 The next step is to form some sort of ILC of these maps to reduce foreground and noise.
