Phase transform T{ χ }, in case when measured (solid black) and expected (dashed black) phase are close. The gray dotted line is the difference χ= ψ ̂ i [n] ψ i 0 [n] between both phases. The transform T{χ} (solid gray) produces a high value at frequency bins relevant for the harmonic sieve (assuming matching phases) and furthermore acts as an unwrapping function.
