# Limb Darkening Calculator

The Limb Darkening Calculator calculates limb-darkening coefficients for a specified stellar model, plotting results versus intensity ratio and wavelength. It uses high spectral resolution stellar atmospheric models, which are a necessity given JWST's expected precision.

The name of a target to resolve in ExoMAST

$$T_\text{eff}$$
K
The stellar effective temperature (3500.0 - 8750.0)
$$\log (g)$$
dex
The logarithm of the stellar surface gravity (3.0 - 5.0)
$$[\text{Fe}/\text{H}]$$
dex
The logarithm of the stellar metallicity (-0.5 - 0.5)

$$\lambda_\text{min}$$
$$\mu$$m
The minimum wavelength to use
$$\lambda_\text{max}$$
$$\mu$$m
The maximum wavelength to use
# channels
The number of channels to use (for grisms)

Minimum $$\mu$$
The minimum angle to consider when fitting the LD profile
