wigner3j
- pyarts.arts.math.wigner3j(j1: pyarts.arts.Rational, j2: pyarts.arts.Rational, j3: pyarts.arts.Rational, m1: pyarts.arts.Rational, m2: pyarts.arts.Rational, m3: pyarts.arts.Rational) float
Computes the Wigner 3J symbol
\[\begin{split}w_3 = \left(\begin{array}{ccc} j_1&j_2&j_3\\m_1&m_2&m_3\end{array}\right)\end{split}\]Note that an appropriately large call to
make_wigner_ready(fastest, largest, 3 or 6)
must have been made ahead of time
