[Pw_forum] ban band number

[Stefano de Gironcoli]

grep -e "ban band" */*.f90    returns the following:

PP/epsilon.f90:  IF ( REAL(nbnd, DP)  <= nelec / 2.0_DP ) CALL 
errore('epsilon', 'ban band number', 1)

I guess that this means you specified a too small value for nbnd.
I also guess that "ban" is a mispelling for "bad"
