Notes. N is the number of sample datapoints; ⟨ ρ ⟩ and P are the most probable correlation coefficient and the probability of the most probable correlation coefficient to occur given no relationship in the sample (cf. text), respectively. The uncertainty of ⟨ ρ ⟩ denotes its 68 % confidence level. Pσ is the significance expressed in terms of σ. We show only the results of parameter pairs which meet the following criteria: | ⟨ ρ ⟩|≥ 0.3 and P ≤ 0.1, or which are of special interest. Parameter pairs are sorted by parameter type. All correlation coefficients were calculated excluding Pluto. Correlation analyses taking η into account are based solely on the 7 floating-η fit solutions. In order to assess the effects of discovery bias, we include the heliocentric distance at the time of discovery r⋆ in our analysis. To improve the readability we refrain from listing all correlation values of the color indices with r⋆ and d. Instead we only show the correlation values of spectral slope with r⋆ and d, which gives similar results.
