stressed that quantitatively the experimental determination of the NLD and RSF is model-dependent, as the method enables a unique determination only of the *functional form* of the NLD and RSF. In order to obtain the absolute value of the total level density (and hence the RSF) from the measured data, the experimental NLD needs to be normalized to the total level density at the neutron separation energy $S_n$, which in turn is derived from the neutron resonance spacing. The parity and spin distributions need to be known to estimate the total level density from the resonance spacing. As shown in Ref. [@go08], uncertainties within a factor of two can still affect this NLD normalization procedure and consequently could affect the low-energy RSF.

This uncertainty has been considered here. In Fig. \[fig00\], the NLDs of $^{93-98}$Mo have been renormalized to the calculated total level densities at $S_n$ taken from Ref. [@go08], which were themselves normalized to available experimental s-wave spacings. One exception is $^{98}$Mo, for which the newly recommended value of the s-wave spacing $D_0 = 60(10)$ eV [@RIPL3] has been adopted. This new value leads to $\rho(S_n) = 1.38(69) \times 10^5$ MeV$^{-1}$ if calculated with the same prescription as in
