GJ 1214b: Exoplanet Phase Curve and Transit Analysis Outputs

Outputs from a fiducial analysis of the exoplanet GJ 1214b, including eclipse depth, transit depth, and nightside flux per wavelength bin. The dataset contains best-fit spectroscopic and white light curves, posterior parameter chains from an MCMC analysis, and scripts for generating plots and calculating phase curve amplitudes. Author Michael Zhang from the University of Chicago produced this data, which is shared under an Open Access license.

Use Cases

• Modeling exoplanet atmospheric properties based on phase curve amplitudes and offsets.
• Comparing first-order and second-order phase curve component analyses using the provided amplitude files.
• Reproducing spectroscopic light curve fits for the 6000–6500 Angstrom wavelength range.
• Validating MCMC sampling results for white light curve system parameters using the provided chain and posterior files.

Strengths

• Includes both spectroscopic and white light curve analysis outputs, providing multiple data views.
• Contains raw MCMC chains (e.g., white_chain.npy) and posterior probabilities, enabling detailed statistical review.
• Provides Jupyter notebook (Generate plots.ipynb) for visualizing results and clarifying data formats.

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.
