Effectively what is done is to start with an initial estimate of the density and velocity distributions, calculate the observed properties (periods of oscillations, travel times, and so forth), compare these with the observations, and then refine the density and velocity distributions until the observed properties are satisfactorily reproduced. An elegant mathematical
