match_name-- Optional wildcard string to match to element names for selection of elements to inculde in the analysis.
start_name-- Name of the element at which to start analysis. If the element occurs more than once, the first occurrence is used.
end_name-- Name of the element at which to end analysis. If the element occurs more than once, the first occurrence is used.
s_start-- Position (in meters) at which to start analysis.
s_end-- Position (in meters) at which to end analysis.
tag-- Name prefix for quantities computed by the analysis. The quantity names will have the form tag.statistic.quantity, where statistic is one of

etayp. E.g., if tag is
