1443	 A Method for Finding the Least Squares Estimate of the Intersection Point of Two Helices in Space	 When the helical trajectories of two charged particles moving away from a common point in a magnetic field are reconstructed from measurements on the tracks the reconstructed tracks are perturbed by measurement and other errors and do not in general intersect. A method is given for adjusting the reconstructed tracks in a least squares manner so that they do intersect.
