In the example 05,
 cat > si.chdens.in << EOF
 &input
    nfile = 1
    filepp(1) = 'sicharge'
    weight(1) = 1.0
    iflag = 2
    plot_out = 1
    output_format = 2
    fileout = 'si.rho.dat'
    e1(1) =1.0, e1(2)=1.0, e1(3) = 0.0,
    e2(1) =0.0, e2(2)=0.0, e2(3) = 1.0,
    nx=56, ny=40


is there anyone who can tell which direction it calculated?
