The imaginary part of the transform.

The article uses the magnitude of the coefficients, which is computed using both the real and the imaginary part.

The phase portion isn't actually just the imaginary part, it's just the piece of information lost when one goes from real+imag -> magnitude, i.e. it's the argument of the complex number.
