The data for "Worlds Next Door. IV. Mapping the Late Stages of Giant Planet Evolution with a Precise Dynamical Mass and Luminosity for eInd Ab"

This repository provides the orbital parameter posteriors for all models discussed in Section 3.5 in "Worlds Next Door. IV. Mapping the Late Stages of Giant Planet Evolution with a Precise Dynamical Mass and Luminosity for eInd Ab" by Sanghi et al. (2026). A sample notebook demonstrates how to access the posterior samples from the individual fits files. Below is the correspondence between the filename and the orbit model. By default, all orbit models use observable-based priors for the relative astrometry and include a GP in the RV model, unless otherwise specified. epsInd_astro-post.fits – Relative astrometry only epsInd_astro_HGCA-post.fits – Relative astrometry + HGCA epsInd_astro_RV-post.fits – Relative astrometry + RV epsInd_NoNIRCam-post.fits – Relative astrometry (No JWST/NIRCam) + HGCA + RV No File. Model did not converge – Relative astrometry + HGCA + RV (No GP) epsInd_allData_noGP_noUVES-post.fits – Relative astrometry + HGCA + RV (No UVES and No GP) epsInd_allData_unipri-post.fits – Relative astrometry (Uniform Priors) + HGCA + RV epsInd_allData_obspri-post.fits – Relative astrometry + HGCA + RV
