In case you wondered why this is defined on DimensionRegion level and not on Region level: the zone sizes (upper limits) of the velocity dimension can indeed differ in the individual dimension regions, depending on which zones of the other dimension types are currently selected. So this is exceptional for the velocity dimension only. All other dimension types have the same dimension zone sizes for every single DimensionRegion (of the sample Region).
