Abstract
Recent experimentation has revealed a discrepancy between the calculated and actual hyperfine structure of the PbF molecule. This discrepancy has been attributed to a misrepresentation of the parity for the ground-state PbF molecule. In a previously published work [Shafer-Ray, Phys. Rev. A 73, 034102 (2006)], we derived a formula for the electric-field-dependent factor of the ground-state PbF molecule with the misassigned parity. In this Addendum, we reformulate that work and derive the factor based on the corrected ground state. We discuss the impact of the corrected factor of the PbF molecule and conclude that the PbF molecule has a factor which can be small enough to perform an experiment sensitive to the electron's electric dipole moment.
