Mirror wavefront error rated < 1/20th wave PV across both diameters

Diffraction edge and smoothness excellent; figure of revolution and polish fine.

Arithmetic wavefront error = 1 / 39.2 wave at zone 2 (average both diameters)

Results for individual diameters:
	Reading Diam1: 1 / 36.8 lambda, Max Trans Aberration=0.11
	Reading Diam2: 1 / 28.4 lambda, Max Trans Aberration=0.31
