A set of nested lists containing tables with reference values at different
z-scores/centiles for valid x values (usually age in days, also
length or height in cm for weight-for-length (wfl) and weight-for-height
(wfh) standards, respectively). The list is ordered by acronym first, then
by sex and finally by z-score/centile.
