For his final analysis, Bucherer recalculated the measured values of five runs with Lorentz's and Abraham's formulas respectively, in order to obtain the charge-to-mass ratio as if the electrons were at rest.
In addition, Bucherer's apparatus was improved in 1909 by his student Kurt Wolz, who also obtained agreement with the Lorentz-Einstein formula (though he didn't compare Abraham's formula with his data, Fig. 7) [REF].
