Optimised constellation for the paper High-Cardinality Geometrical Constellation Shaping for the Nonlinear Fibre Channel. Each file is a constellation optimised for the SNR in dB mentioned in the filename, containing the coordinates of the constellation points as comma-separated values. Each column represents a dimension and each row is a separate constellation point. The bit labels for the generalised mutual information (GMI) are implied and follow natural mapping, the first row is 0,..,0,0 the second 0,...0,1 the third 0,..,1,0 the fourth 0,...,1,1 etc and the last 1,...,1,1. The file named gmi.txt is the GMI for the resulting constellations.
