In the 1980s, measurements of the cumulative $\beta$ spectra of the fission products following the thermal neutron induced fission of $^{ 235}$U, $^{ 239}$Pu, and $^{ 241}$Pu were performed at the magnetic spectrometer BILL at the ILL in Grenoble. This data was published in bins of 250 keV. In this paper, we re-publish the original data in a binning of 50 keV for $^{ 235}$U and 100 keV for $^{ 239}$Pu and $^{ 241}$Pu.
