The observed profile likelihood ratio exclusion limits for the two-dimensional κ<sub>λ</sub> vs. κ<sub>2V</sub> modifier space, shown by the solid dark purple line at the 1σ level and the dashed turquoise line at the 2σ level. The black cross denotes the best-fit values of (κ<sub>λ</sub>,κ<sub>2V</sub>). For both the expected and observed limit plots, the black star indicates the SM prediction (κ<sub>λ</sub>=κ<sub>2V</sub>=1).
