Table 1: Characteristics of PLANCK one year simulations ( upper) and WMAP six year simulations ( lower). PLANCK and 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.
