In this file the detailed data of all structures in the Pareto front are presented. First we indicate the data common to all the structures, then for all structures we report the position and width of each silica groove. All horizontal distances are taken from the same 0 point, which is the centre of the first groove for uniform and linearly chirped configurations. Notice that the MO-PSO algorithm can lead to a change of the centre of the first groove, while the fiber offset is kept fixed.
