The plot represents stringency of nucleosome positioning (at the
dyad) as a fraction of positioned nucleosomes. Stringency metric is
given by a ratio of putative mononucleosome dyad instances falling
in a 23 base pair window of a given site to the number of infringing
nucleosome dyads in a 300 base pair window.
