Plots of closure amplitudes at the X band for source 2229+695 as a function of GMST for two quadrangles, (a) KOKEE–NYALES20–WETTZELL–TSUKUB32 and (b) BADARY–KOKEE–YEBES40M–WETTZELL. See Figure 5 for a description of the plot design. The magnitudes of the patterns in both plots increased, and the changes of the patterns with respect to GMST became more and more rapid.
