Hi Edward. Thanks for looking at this.
The offset for N15 spinlock is given in Hz as parameter deltadof2 for our pulse sequence. So I guess that this conversions should be appropriate: omega_rf_ppm = float(deltadof2) / (set_sfrq * 1E6) * 1E6 where set_sfrq=799.7773991 is the spectrometer frequency.
