nnk : the number of different values of nk to test. Default: integer 5 deltank(3) : the interval between nk values. All three values of nk1, nk2, and nk3 are updated simultaneously. Default: integer 2 2 2 nsigma : the number of smearing intervals. Default: integer 1 deltasigma : the distance between different smearing values (can be either positive or negative). Default: 0.005 Ry flnkconv : file where the data with the k point convergence is written. Default: character(len=*) 'output_nkconv.dat' flpsnkconv : name of the postscript file with the k points convergence plot. Default: character(len=*) 'output_nkconv'
