(a) A scatter plot of the statistical mapping process for the horizontal pointing angle θx. By fitting an ellipse to the sample space of all of the recorded values for θx and times tn and tn+1, we extract (b) a time-dependent probability distribution at time tn+1 that is dependent on the value at time tn. Truncation of the probability distribution along the θx(t + 1) axis is due to the finite width of the covariance ellipse.
