Effects on fNL scatter, simulation-by-simulation, of different levels of noise mismatch, as described in Sect. 6.2. Top: EEE-only results. Bottom: combined T+E results. The magenta line represents the case in which we generate an extra-noise component in harmonic space, both in temperature and polarization, with variance equal to the difference between the noise spectra in the data and the simulations. All other lines represent cases in which we generate extra-noise maps in pixel space, with the rms per pixel extracted from simulations and rescaled by different factors, as specified in the legend; the label “TQU” further specifies the pixel-space test in which extra noise is added to both temperature and polarization data, unlike in the other three pixel-space cases, in which we include only a polarization extra-noise component.
