find_abund(eff_t, surf_g, met, rew, center=670.9659)

Find the abundance based on the stellar parameters and measured reduced equivalent width.

Parameters:

• rew (Real) – The reduced equivalent width for the lithium line at 670.9 nm.

• eff_t (Real) – The effective temperature of the star.

• surf_g (Real) – The log surface gravity of the star.

• met (Real) – The metallicity of the star.

• center (Real, optional) – The center of the lithium line that the input rew corresponds to, in angstroms. The 3 lithium lines are centered at 610.5298, 670.9659, and 812.8606 nm in the Balder results. The input center value will snap to the closest value out of those 3.

Returns:

predcited_li – The predicted lithium abundance.

Return type:

float

_find_abund(eff_t, surf_g, met, rew, ind=1)

Same as find_abund_rew, hidden version without grid checks so extra warnings aren’t thrown. This version can be used to quickly process many rew values.
