Notes. We show the rms (in μK) of binned white noise (“white”), correlated residual noise (“CRN”), and their sum (“full”). All values are averages over 10 noise realizations. “NW” refers to noise weighting, and “HUW” to the horn-uniform weighting scheme. Noise weighting minimizes the total residual noise. In actual mapmaking we instead used horn-uniform weighting to reduce effects from beam-shape mismatch.
