Re: [sr #3124] Grace graphs production for R1rho analysis with R2_eff as function of Omega_eff -- March 13, 2014 - 19:51

Hi,

This is the standard way of calculating theta.  Note that some of the
dispersion models in lib.dispersion do not use this code and actually
calculate a different theta value using the population averaged
spin-lock offset.

Regards,

Edward
