Table 2:

Calculated values of ΔJ₀ and $\Delta {\overline{\kappa }}_{\mathrm{m}}$. These values are obtained by a least-squares fit between $\Delta \Delta {\tilde{F}}_{\text{HC}}$ and $\Delta \Delta {\tilde{F}}_{\text{TI}}$ values. The values are reported in the POPC→POPE sense (i.e., Δ = POPE – POPC). That is, POPE has a stronger negative curvature than POPC, and a less negative ${\overline{\kappa }}_{\mathrm{m}}$. The error for each value was calculated by fits to Monte Carlo generated data sets.
