| Summary:

The mass table in the deformed relativistic Hartree-Bogoliubov theory in
continuum (DRHBc) with the PC-PK1 density functional has been established for
even-$Z$ nuclei with $8le Zle120$, extended from the previous work for
even-even nuclei [Zhang $it{et~al.}$ (DRHBc Mass Table Collaboration), At.
Data Nucl. Data Tables 144, 101488 (2022)]. The calculated binding energies,
two-nucleon and one-neutron 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. A total of 4829 even-$Z$ nuclei are predicted to be bound,
with an rms deviation of 1.477 MeV from the 1244 mass data. Good agreement with
the available experimental odd-even mass differences, $alpha$ decay energies,
and charge radii is also achieved. The description accuracy for nuclear masses
and nucleon separation energies as well as the prediction for drip lines is
compared with the results obtained from other relativistic and nonrelativistic
density functional. The comparison shows that the DRHBc theory with PC-PK1
provides an excellent microscopic description for the masses of even-$Z$
nuclei. The systematics of the nucleon separation energies, odd-even mass
differences, pairing energies, two-nucleon gaps, $alpha$ decay energies, rms
radii, quadrupole deformations, potential energy curves, neutron density
distributions, and neutron mean-field potentials are discussed.
