Results for the minimum separation (top) and time of closest approach (bottom) for the Monte Carlo error analysis between the proper motions of VLA 1623B and VLA 1623W. The solid lines show the median values and the dashed lines show the first quartile (25th per-centile) and third quartile (75th percentile) for each distribution. Note that the minimum separation has an upper limit of 9.3 arcsec, corresponding to the current separation between the two sources.
