The neutron capture cross sections of ${}^{142}\mathrm{Nd}$ and ${}^{144}\mathrm{Nd}$ which were determined recently with the Karlsruhe $4\pi {\mathrm{BaF}}_2$ detector have been reanalyzed at low energies. The parameters of 52 resonances in ${}^{142}\mathrm{Nd}$ and of 78 resonances in ${}^{144}\mathrm{Nd}$ were extracted by means of a shape analysis program, yielding a more reliable determination of the averaged cross sections below 20 keV. This study confirms the previously reported stellar cross sections, so that the $s$-process study based on these data remains unchanged.
