Notes. In each case the adiabatic mode is considered together with one isocurvature mode (either cold dark matter, neutrino density, or neutrino velocity isocurvature). As explained in the text this gives six different fNL parameters, indicated by the different combinations of the adiabatic (a) and isocurvature (i) modes. Results with two significant digits are shown for both an independent and a fully joint analysis, for T-only, E-only, and full T+E. In all cases the ISW-lensing bias has been subtracted.
