Preview image is used for pre-exposure (which we believe is advantageous to reduce beam induced drift due to charging effects) and for final centering of the beam. The first image is taken and defocus defined by "defocus target" and the second image is taken 3 um further from focus. If you don't need focus pairs, simply remove or uncomment the relevant lines.
