The identifier of an entry together with the name (n='...') and the unit (u='...') should give a first hint about the meaning of the quantity. The suffix '_xmean' indicates a simple average. The suffix '_xmean2' indicates the root-mean-square average (note: the simple average is not subtracted).

Some entries (e.g. ferb_xmean) have a hidden b in their name, have one element more (e.g. 121 instead of 120) than most of the others, and are characterized by the ds keyword (see Table 6). These quantities are located at the cell boundaries in contrast to the usual cell-centered quantities. Clearly, there are also two sets of axes (e.g. xc3 and xb3) corresponding to the cell- or boundary-centered quantities.
