I was wondering if someone could help me with the units used in the properties module for linear response calculations. The manual specifies that frequency to be given in hartrees.
To do this, I have 1 GHz = 6.6e-7 eV. This gives me a value of 1 GHz = 2.42e-8 Eh. Is this correct? A 20 GHz frequency would be ~10^-7. This seems suspicious as the example has a value of ~10^-2.
