23.5.26 δc (JIS2001, ISO1997, VDA, Free), Htp (ANSI): Slice-level difference (plateau
ratio)
With the slice level that is set from the mr[c] value as the reference line, δc is the height (or
depth), in µm, from the reference line to slice levels obtained from changing the value of
mr[c]. If the slice level used to obtain the height (or depth) is higher than the reference line,
then the value of δc is positive. If the slice level used to obtain the height (or depth) is
lower than the reference line, then the value of δc is negative.
