Fix behaviour of PSD at zero frequency #27

Closed quantum-charlie closed 3 weeks ago

quantum-charlie commented 3 weeks ago

Taking the ω->0 limit of the PSD should give a non-vanishing contribution at ω=0 , which was not previously included as the noise was forced to zero at ω=0.

Thank you @quantum-charlie for submitting this pr. The change definitely needs implementing. However, the failing test needs to be fixed before it can be merged.
