Fig. 1

The set X is depicted on the real line (bottom): Masses in X are denoted by vertical bars and masses in \(\bar{X}_M \setminus X\) by crosses. On the top, a subgraph of the NC-spectrum graph is shown. Every vertex represents a mass in \(\bar{X}_M\) and an edge connects two vertices if their mass difference is equal to the mass of a string (only edges for strings of length 1 are shown)
