If the band structure analysis is selected, BAND file appears. The
first column is the accumulated distance in the reciprocal
space. The later columns are the frequencies which are square root
of the eigenvalue. The imaginary value is presented as negative
value. The number of first line is the number of frequencies per a
q-point.
