- Parameters:
-
- hyper_lIterable[scalar_like]
The hyperfine structure constants of the lower state (Al, Bl, Cl, ...).
- hyper_uIterable[scalar_like]
The hyperfine structure constants of the upper state (Au, Bu, Cu, ...).
- coeff_lIterable[scalar_like]
The coefficients of the lower state to be multiplied by the constants (coAl, coBl, coCl, ...).
- coeff_uIterable[scalar_like]
The coefficients of the lower state to be multiplied by the constants (coAu, coBu, coCu, ...).
- Returns:
-
- outfloat
