Planck 2015 residual maps of rejected single bolometers (see Planck Collaboration X 2016) and the corresponding NPIPE residual maps. All maps have a smoothing of 60′ FWHM. The fraction in the label of the 857 GHz detectors indicates that the maps are divided by 2 with respect to the colour bar. The overall level of coherent systematic residuals in these maps is dramatically reduced in NPIPE, to the level that all except 857-4 (see text) can now be included in the final analysis.
