Caption: Figure 1.

The on-sky coordinates of a moving object with respect to time. The dashed black line represents a trajectory estimated using least-squares multivariate regression, which does not predict the trajectory accurately, due to the presence of outliers in the data set. The solid black line represents a trajectory estimated using robust multivariate regression utilizing the MCD, which accurately predicts the moving-object trajectory in the presence of outliers.
