Table B.2

Coherence length values extracted from measurements at Lyon, France [5, 13]. ΛG is read in Figure 4a [5] and Figure 7 [13] on the lag axis where the Gaussian lines reach −π/4 ≈ −0.785 and exp(−π/2) ≈ 0.208, respectively. is obtained by present fitting (10) of the original coherence data.
