Dear all, I am trying to plot a 2D charge density for a hexagonal lattice. According to the pp.x input file description, e1(i), i=1,3 is "3D vector which determines the plotting line". Are these 3D vectors based on Cartesian system of coordinates? A (1 0 0) vector is a vector along the x axis or along the V1 vector that is defined as the crystal axis for ibrav 4?
