Different simulations of the LIRGs A_V distribution for increasing distance (from top to bottom and left to right). The median of each distribution is highlighted with a vertical dashed line. The distance and the median A_V of the simulated distribution is annotated in each panel. The top left panel corresponds to the average distance of the ULIRG subsample, and shows the observed A_V distribution of the ULIRGs and its median, in yellow.
