Best-fit values (solid squares) of the widths (upper panel) and amplitudes (bottom panel) of the error beams. Solid lines fit these values to Eq. (14) (upper panel) and Eq. (15) (bottom panel) in order to obtain the correlation length (L) and the RMS value of the surface errors (σ). For a more detailed explanation, see Sect. 6.4.
