Point detector measurements: comparison of the data recorded as line scans in specular condition with background subtraction and the curve recorded as a result of rocking scans at each point. This last measurement took about 8 h (1 s exposure per point). In one case, the data are also simulated and fitted to retrieve the thickness and roughness of the layers (see text for details). Note, for the last mentioned data, the interference at q ∼0.17 Å−1 which is much more visible. (Inset) The structure of the soliton sample (the thickness and materials of the different layers). |
