Figure 6
The profile of a high and low mosaic spread reflection of equal total intensity as a function of φ angle. For a low mosaic spread reflection, a 1° oscillation image will encompass the whole reflection, which will thus be `fully recorded'. For a reflection with larger mosaic spread, the same reflection intensity is detected over three consecutive 1° images, and is `partially recorded' on the (n − 1)th, nth and (n + 1)th images. To obtain the full reflection intensity, these images must be scaled together after integration, resulting in higher errors (σs) on the measurements. |
