Notes. % refers to the percentage of Kiwi-GA runs for which we found a significant positive or negative correlation for the relevant parameter combination. The mean value of τ_k is computed separately for the significant positive, and significant negative values of τ_k. In dark and light blue we mark parameter combinations for which we find a significant correlation for at least 75% or at least 50% of our runs, respectively. The results presented here should be regarded as an indication of possible correlations given the adopted set of diagnostics and the parameter space covered by our sample, and cannot necessarily be generalised.
