Extended Data Fig. 7: Breakdown of uncertainties.
From: Sterile-neutrino search based on 259 days of KATRIN data
Uncertainty breakdown for the combined dataset with \({m}_{{\rm{\nu }}}^{2}=0\,{{\rm{eV}}}^{2}\). The plot focuses on the region \({m}_{4}^{2} > 1\,{{\rm{eV}}}^{2}\). The 68.3% C.L. sensitivities on \({\sin }^{2}({\theta }_{ee})\) for individual systematic effects and the statistical-only contour are displayed. Notably, all systematic effects are minor compared to the statistical uncertainty. The statistical uncertainty predominates over the combined systematic uncertainties across all \({m}_{4}^{2}\) values.
