Joint probability distribution of the predicted peculiar velocity extracted at the positions of galaxies in all validation samples and the peculiar velocity values listed in the A-SIM galaxy catalog. The three panels correspond to the x-, y-, and z-components of the peculiar velocity from left to right, respectively. The white solid lines represent the 1σ and 2σ confidence level contours of the distribution. The red dashed diagonal line represents the one-to-one relation for reference. Pearson correlation coefficients between predicted peculiar velocities and those from the galaxy catalog are 0.52 ± 0.11 for the x-, 0.43 ± 0.12 for the y-, and 0.48 ± 0.12 for the z-components of the velocity field (mean and 1σ standard deviation across all validation samples).
