\caption{Characteristics of {\sc planck} one year simulations ({\it upper}) and {\sc wmap} six year simulations ({ \it lower}). {\sc planck} and {\sc wmap} hit counts correspond to $1.7'$ (Healpix $n_{\rm side}=2048$) and $6.8'$ ($n_{\rm side}=512$)~pixels respectively. $N_{\ell}$ is the white noise level calculated from  the inhomogeneous distribution of hits.}\label{tab:freqchann_Planck}
