Include/ neglect frequency modulation due to magnetic field changes
It seems like it is working. When I test all 4 possibilities, the powers in the sidebands are approximately all the same, but they do differ on the percent level. Presumably for very low pitch betas, magnetic_modulation will be more and more important
The Bessel style calculation is retained when harmonic == True and magnetic_modulation == False
Merge: added feature to allow for both
