Notes.
ZASPE = Zonal Atmospherical Stellar Parameter Estimator routine for the analysis of high-resolution spectra (Brahm et al. 2015), applied to the FEROS spectra of HATS-13and HATS-14. These parameters rely primarily on ZASPE, but have a small dependence also on the iterative analysis incorporating the isochrone search and global modeling of the data.
From APASS DR6 for HATS-13, HATS-14as listed in the UCAC 4 catalog (Zacharias et al. 2012).
YY+ρ⋆+ZASPE = Based on the YY isochrones (Yi et al. 2001), ρ⋆ as a luminosity indicator, and the ZASPE results.
The parameter ρ⋆ is primarily determined from the global fit to the light curves and RV data. The value shown here also has a slight dependence on the stellar models and ZASPE parameters due to restricting the posterior distribution to combinations of [ρ⋆,Teff ⋆,Fe / H] that match to a YY stellar model.
