The lower boundary of this window is somewhat lower than the 
separation energy you choose in lstart (default -6.0). It doesn't make 
sense to choose a much lower value for this window, as your choice in 
lstart implies that there shouldn't be eigenvalues in that range. (and 
a higher lower boundary is of course wrong as well, as it would 
exclude eigenvalues from the window).
