Planetary radius measurements in literature have uncertainties about 40% larger than we measure in this work.

The attached plot shows the revised #exoplanet radius and mass, along with the difference between ours and those in #TEPCat (astro.keele.ac.uk/jkt/tepcat/).

Our stellar radii have uncertainties of about 2%, and we measure stellar temperatures to around 50K.

Using synthetic #Gaia #DR3 G-band photometry, our parameters show a factor of 10 reduction in RMS residual and nearly a 40% improvement in mean uncertainty, when compared to the literature.

In this article, we use SED fitting to re-derive the fundamental parameters of known #exoplanet hosting #stars. We also use literature data, or in some cases fitting of new #TESS #transit data, to re-derive #exoplanet properties.
