Z-stack observations are when the instrument collects data from the same location at several different focus positions. We are planning Z-stacks with ChemCam’s black-and-white camera and the main spectroscopy laser to make sure that we get good data from the target, and to collect information to develop new focusing methods for ChemCam…” [More at link]
