Figure 7.

A, Dispersion profiles of three estimates of an average relaxation rate R ₁—the reciprocal of the arithmetic mean T₁, of the geometric mean T₁, and of the best‐fit single‐exponential decay rate. The solid lines represent the multi‐Lorentzian models (Equation 4), which are plotted using the correlation time distributions $g({\tilde{\tau }}_c)$ shown on the right. B, Mean correlation times $<{\tilde{\tau }}_c{>}_g$ computed from the given $g({\tilde{\tau }}_c)$ for each of the three R₁ estimates. The means based on the $<T_1{>}_g^{}$ values (see the blue profiles) consistently increase after the trypsin digestion of cartilage
