Ground-state properties of even–even nuclei with 8 ≤ Z ≤ 120 from the proton drip line to the
neutron drip line have been investigated using the deformed relativistic Hartree–Bogoliubov theory
in continuum (DRHBc) with the density functional PC-PK1. With the effects of deformation and
continuum included simultaneously, 2583 even–even nuclei are predicted to be bound. The calculated
binding energies, two-nucleon separation energies, root-mean-square (rms) radii of neutron, proton,
matter, and charge distributions, quadrupole deformations, and neutron and proton Fermi surfaces
are tabulated and compared with available experimental data. The rms deviation from the 637 mass
data is 1.518 MeV, providing one of the best microscopic descriptions for nuclear masses. The drip
lines obtained from DRHBc calculations are compared with other calculations, including the spherical
relativistic continuum Hartree–Bogoliubov (RCHB) and triaxial relativistic Hartree–Bogoliubov (TRHB)
