Distributions of the peculiar motions |v_p|, LOS velocity difference from circular motion |v_los − v_c,losI, and the difference between the kinematic and true distance |d_k − d_true|. The dashed vertical lines on the histograms indicate the 5%, 20%, 80% and 95% percentiles of the distributions. There is a power-law correlation between the peculiar velocity and LOS velocity deviation of slope α = 1.1 (middle-left plot). Similarly, there is a power-law correlation between the LOS deviations from circular velocity and the resulting distance error (bottom-middle plot) with a slope α = 0.94.
