February 2, Revised Manuscript: Woo studied the EW distribution and compared it with the two-parameter Weibull and gamma distributions with respect to failure rate. Particularly, it is shown how the proposed EW distribution offers an excellent fit to simulation and experimental data under all aperture averaging conditions, under weak and moderate turbulence conditions, as well as for point-like apertures.
