    • We have observed sharp peaks in [Formula Presented] at some specific values of [Formula Presented] as a result of almost degenerate energy levels. We have gotten rid of this finite size effect by discarding the values of [Formula Presented] which are 100 times larger than the average value. This does not change the value of the asymmetry [Formula Presented] for the self-dual point [Formula Presented] since the increase at this point is not due to some quasidegeneracy, but to the fact that almost all eigenvalues are clustered in pairs of close values
    • We have observed sharp peaks in δ at some specific values of h/J as a result of almost degenerate energy levels. We have gotten rid of this finite size effect by discarding the values of δi which are 100 times larger than the average value. This does not change the value of the asymmetry δ for the self-dual point h/J=1 since the increase at this point is not due to some quasidegeneracy, but to the fact that almost all eigenvalues are clustered in pairs of close values.
