Currently the returned amplitudes are from the multi-gaussian fitting, which takes into account all the gaussians at once. If there are overlapping gaussians, the amplitude for any given fitted gaussian is contingent upon the others. This defies our expectation of what amplitude is, which is the distance between the 1/f background and the amplitude at the center frequency.

Solution: after multifitting, overwrite the amplitude as the distance between the final background and the amplitude at each center frequency.
