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
