Mirror wavefront error <= 1/16th wave across both diameters

Polish, diffraction edge, figure of revolution, and smoothness all excellent.

Arithmetic wavefront error = 1 / 19.1 wave at zone 2 (averaged both diameters)

Results for individual readings:
	Reading Diam1-1: 1 / 18.9 lambda, Max Trans Aberration=0.32
	Reading Diam1-2: 1 / 19.8 lambda, Max Trans Aberration=0.19
	Reading Diam2-1: 1 / 15.9 lambda, Max Trans Aberration=0.27
	Reading Diam2-2: 1 / 16.4 lambda, Max Trans Aberration=0.32
