Relax disp.spin lock offset+field

In the literature, the values are often stated as "offset", "carrier offset", "offset of the spin-lock pulse" with values given in Hz, and can have values from 0-500 to 10-20.000 Hz.<br>
These values reflects offset frequencies to the carrier frequency, and in relax is noted as '''"Spin-lock offset, the frequency of of the rf field"''' : $\mathbf{\omega_{rf}}$.
 
Note that $\Omega_S$ is dependent of the [[wikipedia:Chemical_shift | chemical shifts]] $\delta$ in ppm for the nuclei of interest, and is first calculated later.
Relax needs input in ppm, and converts to the rad/s, with the following function calls.
