Figures 5 and 6 and their captions in the above paper were interchanged. The correct text and numbering are shown below.  Figure 5. A comparison between the KrF^* densities using the single-state and two-state models for the upper laser level. The plots in figures 4 show the temporal evolution of 16 selected discharge species whose densities were at least three orders of magnitude higher than the rest. It was computed that, during the quasi-steady phase, the respective densities for excited-state manifolds of Kr^* and Kr^** decreased by more than an order of magnitude while that of the vibrationally excited KrF^** species remained fairly steady.  Figure 6. Comparisons between the computed (full line) and measured (dotted) discharge waveforms. V, voltage; I, current; and V_d, the computed laser-channel voltage. The Kr₂^* species was found to contribute to the photon-absorbing species Kr₂F^*. The computed results showed that ECQ of the KrF^*, KrF^** and Kr₂F^* species contributed to the rising atomic density of F. On the other hand, ECQ reduced the He^* metastable species density. The density of He^*₂ was increased mainly the electron - ion recombination excitation, e^-+He₂⁺. The rates of formation of excited KrF molecules were compared for two separate cases of (i) one-state and (ii) two-state upper laser levels shown in figure 5.
