Figure 9
Plots of the VL signal versus qz, (a), (b) and (c) for the upper VL Bragg reflection from YBa2Cu3O7 at 23 T (see Fig. 5) and (d), (e) and (f) for the lower VL Bragg reflection from YBa2Cu3O7 at 25 T. In panels (a), (b), (d) and (e) the magnet angle α is written in the figure. (c), (f) Data after combination of the two angles shown in panels (a) and (b), and (d) and (e), respectively. From the 23 T panels, we can see that the 1.2° data [panel (a)] make no contribution to the final combination in panel (c) and only add noise. From the 25 T panels, we can see that the noise is heavily reduced when combining both angles in panel (f). Note that some data points appear to have zero error: this is because the data are zero. |
