Adaptations of the Fermilab E69 event reconstruction program were made to increase its speed and versatility. An attempt to increase the number of chambers utilized per track prompted the examination of a new track selection criterion, the linear correlation probability. A comparative study of the merits of the probability of linear correlation, as opposed to the reduced chi square, for determination of tracks shows that, for a limited set of track parameters, the linear correlation probability works better than the x2/v. For optimized parameters the x2/v selection criterion has a slightly finer resolution. However, the linear correlation can achieve nearly the same resolution involving less computer time. In general the x2/v should remain the preferred choice for accurate tracking while the linear correlation probability should be used for rapid track reconstruction suffering a 1% loss in resolution.
