通知你,通常参考依赖地磁学中使用的方程是:——Langel, r。第四章:主要领域。”Geomagnetism, edited by JA Jacobs (1987). If it wasn't for lockdown I'd have copied from the book locked in my office to make sure I got it right...but until someone corrects me... The Schmidt quasi/semi-normalisations for the associated Legendre polynomials are given by these recursions, in the form you'd actually use for calculations typically:
 "S_{n,0}=S_{n-1,0}\left ( \frac{2n-1}{n} \right )")
Note that if you use Schmidt normalisation of Legendre polynomials from a given software language to do calculations, you *do not* want to include the Condon-Shortley phase factor of
. So check if it is included in the Legendre polynomial and/or normalisation formula. Edit: Some links to open source geomagnetism compatible software for calculating Schmidt normalised associated Legendre polynomials.
