ExoTiC-LD: Stellar Model Grids for Limb-Darkening Calculations

Data required for the ExoTiC-LD GitHub package, including stellar model grids and instrument throughputs. The collection includes a 1D Kurucz grid, a 3D Stagger-grid from Magic et al. (2015), and an extended MPS-ATLAS library from Kostogryz (2022). It was authored by Hannah R. Wakeford of the University of Bristol.

Use Cases

• Calculate limb-darkening coefficients for exoplanet transit observations based on the provided stellar model grids.
• Model stellar atmospheres using the 1D Kurucz and 3D Stagger-grid data mentioned in the description.
• Generate synthetic spectra for different stellar types using the extended MPS-ATLAS library.
• Simulate instrument-specific wavelength responses for observations using the provided sensitivity files.

Strengths

• Includes multiple established stellar model grids: a 1D Kurucz grid and a 3D Stagger-grid from a 2015 publication.
• Features an extended MPS-ATLAS library of model atmospheres and spectra from a 2022 study with a DOI.
• Provides instrument throughput files required for accurate wavelength-specific calculations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
