Comparison of different conversions of the ILL electron data for . Black curve: cross-check of results from [19] following the same procedure. Red curve: results from [22]. Green curve: results from [32] using the same description of decay as in [22]. Blue curve: update of the results from [22], including corrections to the Fermi theory as explained in the text. The thin error bars show the theory errors from the effective nuclear charge and weak magnetism. The thick error bars are the statistical errors.
