Table D.1.
Atmospheric parameters of VHS 1256-1257 b inferred from different wavelength ranges, using ForMoSA and the ATMO model grid. We use NC for "no constraint". The error bars given here are purely statistical and derived from the propagation of the small error bars of our data through the Bayesian inversion. The method used to estimate the final values is described in Appendix D.
