The data for "Updated Mutual Inclination Measurement for 14 Her b and c"

RVAst_mcmc_14Her.py: the source code to perform joint fitting of radial velocity (RV) and Hipparcos-Gaia astrometry data. The detailed methodology are presented in Feng et.al (2023) and Xiao et.al (2024). HD145675_RVAst_posterior_010.txt: the posterior distribution of fitting parameters generated by the code. The basic fitting parameters include the orbital period, RV semi-amplitude, eccentricity, argument of periastron of stellar reflex motion, orbital inclination, longitude of ascending node, mean anomaly at the minimum epoch of RV data and five astrometric offsets of barycenter relative to GDR3. *png/pdf: resulting figures. *vels: RV data from different instruments *gost.csv: the synthetic Gaia epoch data generated from Gaia Observation Forecast Tool *hip2.abs: Hipparcos Intermediate Astrometric Data (IAD) *hg123: Astrometric measurements of HIpparcos and Gaia DR2 & DR3 *Image.rel1: direct imaging data of JWST
