Notes. The quoted value is the noise that is obtained on the map after one second of integration, i.e., about 180 hits for one bolometer. This gives the noise characteristics of bolometers, inverse quadratically averaged over the similar ones within a channel (“P” is for polarization sensitive bolometers and “S” for spider-web unpolarized bolometers). The second column gives the white noise level measured on the power spectrum in the range of 0.6 to 2.5 Hz. The third column gives the total noise, i.e., the rms noise at the map level for one second of integration time of a single detector. The next column recalls the goal stated before launch by Lamarre et al. (2010). Note that the mean integration time per detector per (1.7′)² pixel is 0.56 s for the 100−353 GHz channels and 0.63 s for 545 and 857 GHz, for the nominal mission (see Fig. 21).
