Mirror wavefront error < 1/25th wave PV across both diameters

Polish, diffraction edge, figure of revolution, and smoothness all excellent.
	
Arithmetic wavefront error = 1 / 41.0 wave at zone 3 (average both diameters)

Results for individual sets of readings:
	Reading Diam1-1: 1 / 35.1 lambda, Max Trans Aberration=0.30
	Reading Diam1-2: 1 / 35.0 lambda, Max Trans Aberration=0.24
	Reading Diam2-1: 1 / 31.7 lambda, Max Trans Aberration=0.30
	Reading Diam2-2: 1 / 49.3 lambda, Max Trans Aberration=0.24
