This spectrum is the result of real-time flute modelling. The acoustic model for the calculation agrees well with experiment for the hundred or so that we have measured.

This graph is a theoretical prediction of the acoustic response of the flute. Roughly speaking, it is a measure of how hard it is to make the flute resonate at any given frequency. The flute will play at most of the minima on this curve, provided that the minimum is deep enough and that the neighbouring minima are not too deep or too close.

More precisely, the curve shows the magnitude of the acoustic impedance as a function of frequency. See Flute acoustics and What is acoustic impedance? for more details.
