Figure 3
Signal profiles (evaluated by averaging the signal over 30 pixels) of the nylon wire at four different angular positions along one flank of the rocking curve of the analyzer: $[\Delta\theta]$ = 0 (a), $[\Delta\theta]$ = 5.6 µrad (b), $[\Delta\theta]$ = 11.2 µrad (c) and $[\Delta\theta]$ = 16.8 µrad (d). The PB profile, related to a sample-to-detector distance of 5.5 m, appears in each plot for comparison with the signals obtained in the AB and HI configurations.
