-There will be an output file with the energy levels and their occupation. The last one can be easily found... +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 one column from the output file and from the EIG file. The Fermi energy (**Ef** in a.u., is the energy of the highest occupied value) must be entered in the **eldplot.py** script. Use the command **python eldplot.py** to get the energy level diagram as a postscript image. (use gs to visualize it). Identify the occupied and unoccupied energy levels and name them. Feel free to change the png image names.
