Height distribution of all the transition rates in Eq. (4) for Case f10E25d3 at 6.0 s. Red lines represent the transitions between levels 0 and 1: n₀C₀₁ (red solid line), n₁C₁₀ (red dotted line), n₀R₀₁ (red dashed line), n₁A₁₀ (red dotted-dashed line), and (red three-dotted-dashed line). Blue lines represent transitions between levels 1 and 2: n₁C₁₂ (blue solid line) and n₂C₂₁ (blue dotted line). Yellow lines represent transitions between level 1 and the continuum: n₁C_1c (yellow solid line), n_cC_c1 (yellow dotted line), n₁R_1c (yellow dashed line), and n_cR_c1 (yellow dotted-dashed line). The net rate dn₁/dt is plotted as the green line.
