Log:
Updated the 'No Rex' dispersion model description in the relax manual.
The universal nature of the model is now described, including the addition of
the off-resonance CPMG
and R1rho equations for the absence of chemical exchange. The R1 parameter
optimisation is also
shortly covered.

This model is provided for model selection purposes.
In combination with frequentist methods, such as AIC\index{model
selection!AIC}, or Bayesian methods\index{model selection!Bayesian} it can
show if the presence of chemical exchange is statistically significant.
Optimisation is still required as one $\Rtwozero$ value per magnetic field
strength will be fit to the measured data for each spin system.
+If off-resonance CPMG or $\Ronerho$ data is being used, then one of the
following equations will be fit:
+\begin{subequations}
+\begin{align}
+ \Rtwoeff &= \Rone \cos^2\theta + \Rtwozero \sin^2\theta, \\
+ \Ronerho &= \Rone \cos^2\theta + \Ronerhoprime \sin^2\theta.
+\end{align}
+\end{subequations}
+
+The $\Rone$ value can either be fixed to loaded experimental values or
optimised.
It is selected by setting the model to `No Rex'.
