Probability distribution functions (PDFs) of the mean offsets of the 22 confirmed C-19 member stars from the orbit in velocity (Δv) and position (Δϕ₂), along with the corresponding dispersions, σ_v and σ_ϕ2. The bottom left-hand panels shows the two-dimensional PDF, taken directly from the Markov chain Monte Carlo sampling; the histograms display the marginalized one-dimensional PDFs for the three parameters.
