Table 1 Overview of the range of timings of the different steps for sanding and polishing, imaging and analysis of the beech discs and increment cores and the resulting dimensions and size (in GB) of the final images. Note that mounting, programming and polishing of increment cores is given for the entire batch, as they are small enough to be polished at once. K = \(10^3\), M = \(10^6\)
