We tabulate the atomic mass excesses and binding energies, ground-stateshell-plus-pairing corrections, ground-state microscopic corrections, andnuclear ground-state deformations of 9318 nuclei ranging from $^{16}$O to$A=339$. The calculations are based on the finite-range droplet macroscopicmodel and the folded-Yukawa single-particle microscopic model. Relative to ourFRDM(1992) mass table in {\sc Atomic Data and Nuclear Data Tables} [{\bf 59}185 (1995)], the results are obtained in the same model, but with considerablyimproved treatment of deformation and fewer of the approximations that werenecessary earlier, due to limitations in computer power. The more accurateexecution of the model and the more extensive and more accurate experimentalmass data base now available allows us to determine one additionalmacroscopic-model parameter, the density-symmetry coefficient $L$, which wasnot varied in the previous calculation, but set to zero. Because we now realizethat the FRDM is inaccurate for some highly deformed shapes occurring infission, because some effects are derived in terms of perturbations around asphere, we only adjust its macroscopic parameters to ground-state masses. Thevalues of ten constants are determined directly from an optimization to fitground-state masses of 2149 nuclei ranging from $^{16}$O to $^{265}_{106}$Sgand $^{264}_{108}$Hs. The error of the mass model is 0.5595~MeV. We alsoprovide masses in the FRLDM, which in the more accurate treatments now has anerror of 0.6618 MeV. But in contrast to the FRDM, it is suitable for studies offission and has been extensively so applied elsewhere, with FRLDM(2002)constants. The FRLDM(2012) fits 31 fission barrier heights from $^{70}$Se to$^{252}$Cf with a root-mean-square deviation of 1.052 MeV.
