 There will be an output file with the unoccupied energy levels and the last "**EIG**" file with occupied energy levels.
-To plot the energy level diagram, copy and paste following lines into the python script **eldplot.py**. The file **energy.dat** contains energy eigenvalues (in a.u.) in a column from the output file at the previous step. The Fermi energy (**Ef** in a.u.) must be entered in the **eldplot.py** script. Use command **python eldplot.py** to get the energy level diagram as a png image. Identify the occupied and unoccupied energy levels and name them. Feel free to change the png image names.
