Abstract: Sample and diffractometer alignment for grazing-incidence x-ray measurements become ever more crucial once the beam and surface area of interest reach the nanometre scale. Here we show how a point of interest on a surface can be kept in the beam while measuring x-ray reflectivity, even if it is not in the centre of rotation, either by systematic errors or by additional unwanted angle-dependent sample movement. This can be achieved by a 1D trajectory scan varying the angle of incidence ($\theta$), the detector angle ($2\theta$) and the position of the sample along one axis in the scattering plane. As an example we show the results of x-ray reflectivity measured from a 10$\times$10 $\mu$m$^2$ Au island using a 90 nm beam. Data analysis is presented which considers the angle-dependent x-ray beam footprint illuminating both the Au island and the surrounding support.
