Notes. We consider FFP10 simulations and add extra noise to them. We then measure 
using the Modal 1 pipeline, normalized and calibrated without the extra-noise component. We verify how this affects the local fNL errors (σfNL columns) and measure the standard deviation of the scatter 
, where 
and 
are the measurements extracted with and without noise mismatch, respectively, for the ith simulation (σΔfNL columns). Results in the first row are obtained by generating extra noise in harmonic space, while in the second row we generate extra noise in pixel space, both in temperature and polarization. In the following rows, we still generate noise in pixel space, but leave temperature noise maps unchanged, while scaling the polarization rms by the given factors.
