If no {{:R1 }} values has been loaded, but the <code>R1_fit </code> flag has been turned on, the {{:R1 }} will be fitted as well.
For data without a loaded offset, (see also [[Relax_disp.spin_lock_offset%2Bfield | relaxx relax disp.spin lock offset+field]] ), if <br>
<math>
\bar{\Omega}_{S,i} = 0.0
</math>
Therefore the fitted {{:R1 }} values have no meaning for "No Rex" model, if there is no offset. <br>
