This supplement contains the two tables described in § 3 and two extra tables for references.
Table 1 contains a list of all quintuples whereis the minimal polynomial of a Salem number of degree 6 and . The preperiod m and period p of the beta expansion for are listed in Table 1 if they satisfy m < 10000 and p < 10000.
Table 2 contains a list of for provided . This includes 18 values for which only a lower bound on D = m+p is known.
Table 3 contains periods and preperiods m < 1000, p < 1000 up to trace 15.
Table 4 contains large periods for trace at most 15.
