The figure shows convergence of the absolute energy (blue line) and atomization energy (orange line) of a Zr dimer relative to completely converged numbers (plane-wave calculation at 1500 eV). Also shown are finite-difference and LCAO (dzp) calculations at gridspacings 0.143 Å, 0.167 Å and 0.200 Å.
