Notes.
Confidence masks in temperature and polarization are provided by each method to define where the CMB maps are to be trusted. The preferred masks are common ones adopted for further analysis of the maps, see text for details.
Values in brackets are standard deviations of half-mission half-difference maps, giving an indication of the level of residual noise and systematic effects. Standard deviations of Q and U have been computed from high-pass filtered maps. For details of the downgrading and high-pass filtering procedures, see text.
