SUMMARY
The method of constructing smooth apparent polar wander paths by fitting to small circle arcs is re-examined. The calculation of the best fitting small circle axis and angle is carried out by means of an iterative, rapidly convergent method. In addition, statistical properties are derived for the various estimated parameters in the linear asymptotic approximation, which allows, in particular, the determination of ellipses of confidence around the calculated poles of the model… Expand
