Calibrated Average P-V value of 20 repeated measurements of a high-quality flat with surface error.

Repeatability of a three-flat test. Flat ‘A’ is tested six times using a three-flat test, using six pairs of flats B, C, D, and E to complete six three-flat combinations using 16 phase averages per data per set. This represents the 2σ value from the six three-flat tests. Relative system accuracy for testing is dependent on the quality of the reference optic.

1σ of RMS for 10 data sets, each an average of 10 data sets where each data set is a pixel-by-pixel average of 16 individual measurements on an optical flat.
