How to check for spin contamination in CP2K

Hi Vladimir,

I've attached one of my input and output files. 
I have been using smearing based on reading that it is necessary for 
convergence in metallic systems. Do you know if there is a way to calculate 
how much contamination there in CP2K if smearing is implemented?
