A question about .evec output unit (eigenvalue)

[YouhwanJo]

Hello!

I wish to know what is the unit of eigenvalues in .evec output.

## kpoint       1 :    0.000000e+00   0.000000e+00   0.000000e+00
### mode        1 :    1.000000e-30 
  -0.000000e+00   0.000000e+00
  -0.000000e+00   0.000000e+00
  -7.071068e-01  -0.000000e+00
  -0.000000e+00   0.000000e+00
  -0.000000e+00  -0.000000e+00
  -7.071068e-01  -0.000000e+00

### mode        2 :    1.000000e-30
  -0.000000e+00   0.000000e+00
  -7.071068e-01  -0.000000e+00
  -0.000000e+00  -0.000000e+00
  -0.000000e+00  -0.000000e+00
  -7.071068e-01  -0.000000e+00
  -0.000000e+00  -0.000000e+00

### mode        3 :    1.000000e-30
  -7.071068e-01   0.000000e+00
  -0.000000e+00   0.000000e+00
  -0.000000e+00   0.000000e+00
  -7.071068e-01  -0.000000e+00
  -0.000000e+00  -0.000000e+00
  -0.000000e+00  -0.000000e+00

### mode        4 :    1.661462e-04 **<- this one**
  -7.071068e-01  -0.000000e+00
   0.000000e+00   0.000000e+00
   0.000000e+00  -0.000000e+00
   7.071068e-01   0.000000e+00
   0.000000e+00   0.000000e+00
   0.000000e+00   0.000000e+00

I figured out that from source codes, the eigenvalue is omega^2 , but not so sure about its unit. omega out of it doesn't look like either THz or cm^-1.

Thank you!

Oops, it is Rydberg, already written on the document.. sorry!
