Wigner_D edit page

compute the Wigner d and Wigner D functions Note that for rot = pi/2 and high L the relative error of some matrix entries of the Wigner-d matrix increase rapidly. Moreover the matrix is no longer symmetric w.r.t. d(k,l)=d(-k,l).


Dmn = Wigner_D(L,rot)
dmn = Wigner_D(L,beta)


L harmonic degree
rot rotation
beta second Euler angle


Dmn Wigner D matrix D_L^(m,n)
dmn Wigner d matrix d_L^(m,n)
