Dear CP2K community,
I am a complete beginner in using CP2K. I'm using PBE0+D3/aug-cc-pVDZ for 
 geometry  optimization. The structure is one hydrogen ion and two water 
molecules.
After geometry  optimization, I do VIBRATIONAL_ANALYSIS using optimized 
structure, because I want to know whether my structure is stable. If there 
is no imaginary frequency, I think my structure is OK. But in the output 
file of  VIBRATIONAL_ANALYSIS, there are many asterisks.

 VIB|                                           13                         
        14                   15
 VIB|Frequency (cm^-1)     3851.241875          3870.236967         
************
 VIB|Intensities                           0.000000             0.000000   
          0.000000
 VIB|Red.Masses (a.u.)             1.072537             1.086576           
  1.071116
 VIB|Frc consts (a.u.)                 0.604071             0.624141       
  ************

This are my input files, output files and optimized structure.  I don't 
know what went wrong
Can anyone give me some suggestions?  Any  suggestions are highly 
appreciated.

Best,
Mengxu Li
