(a) Dimensionless fusion (unwrapping) time $t_f/t_f^{\ast }$ versus virion size R/R* at various e_f0 and ${\tilde{\rho }}_f$, from equations (2.5) (with t_b substituted with t_f) and (3.9) and from equation (B 6) from appendix B; (b) Minimum fusion pore energy e_RLγ required to promote membrane fusion at the limiting conditions of budding, as described in equation (3.11), versus ρ_f0/ρ_f (ratio of TP densities host-to-mother) for various equilibrium TP densities $\tilde{\rho }$ in the mother cell.
