Notes

1As will be discussed below, the absorption will be measured as part of the line-up procedure.

2Much in the same spirit as that discussed by Sabine et al. (1995BB13).

3We do not at present know the point spread function of the IP, and for the FWHM widths we have used the nominal pixel resolution of 25 µm.

4In principle the beam divergence parameters [delta]h and [delta]v should be measured. Unfortunately the means for this was not available during the experimental time at the beamline at MAX-lab, but the values in Fig. 6[link] are quite reasonable estimates. The finite Darwin width of the monochromator crystal can be neglected here in evaluating [Delta][lambda]/[lambda].
