Joint posterior distributions of various physical quantities and SFHs retrieved from three different SED fitting runs, for an example quiescent galaxy at z_spec = 0.842. In the cornerplot, we present the posterior distributions of ${\widehat{\tau }}_{\mathrm{dust},2}$, sSFR, t_⋆, mw, Z_⋆, and M_⋆. We compare the posterior distributions of our fiducial run (spectroscopy+photometry, orange) with those from the spectroscopy-only (teal) and photometry-only (purple) run. The contours enclose 20%, 50% and 80% of the total data, of each fitting run. The vertical black dashed line indicates the best-fit value of each physical quantity from our fiducial run. The inset in the right corner of the figure contains the SFH posteriors for each fitting run.
