The AC simulation lists only imaginary part of the output if a spice DC source flag 'extract' is set to True. In normal conditions IO data returns a list of frequencies and corresponding complex value vr+vi. However, with 'extract=True', it returns list of frequencies and corresponding imaginary part vi.
