The plots have two sections.
The number in square brackets in the legend indicates the bin number of the bin giving the exclusion (remember, at present Contur only uses the most discrepant bin, as a conservative way of accounting for correlated uncertainties). The number next to it is the c.l. of the exclusion from that bin (i.e. 1-p).
The main index page starts with the overall exclusion, and then the plots from each category which gave this exclusion (only the most discrepant from each category is used). Below this is a comprehensive list of all plots considered, along with links to the experimental papers and the plots themselves.
