=== The trouble ===
The trouble is.
Does the Hz frequency refers to RF fields applied at the 1H Larmor frequency or 15N frequency?
At page 1708 is states that w_1S = w_1 and w_eS = w_e.
And in pulse sequence it states that:

=== Varian / VnmrJ ===
In some pulse sequences, the following is seen:
'trim' is a basic timeunit and the total spinlock time is calculated as '''2.0*ncyc*trim'''
b1 = getval("b1"), /* spin-lock field, Hz! */
deltadof2 = getval("deltadof2"), /* offset for N15 spinlock */
