Flight-path lengths have been measured by laser techniques for the 200-, 80-, and 18-m stations along flight path 1, and for the 5-, 20-, 40-, and 150-m stations along flight path 6 at the Oak Ridge Electron Linear Accelerator (ORELA). In each case the distance evaluated from the measurements is the slope distance from the center of the neutron-producing target to a position along the beam path, directly above a suitable benchmark at the experiment station. A total of 25 laser measurements were performed between the various stations. These data, along with appropriate uncertainties, were combined using Bayes' method. From this analysis we obtained the desired flight-path lengths, which typically have uncertainties less than 1.5 mm. The measurment technique, uncertainties, analysis method, and results are documented in detail in this report.
