If G is a spectrum object G.EminPole returns a list of length G.N stating a rough estimate of the minimal energy of the eigen-state of the Hamiltonian that caries non-negligible spectral weight. Due to number-loss and orthogonality problems this energy might be much lower than realistic possible. If you need the true value calculate the lowest eigenstate of the Hamiltonian starting from $T\times\psi$.
Print the minimal energy of the poles used in the spectra calculated in the definitions file for spectra.
