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
