Our fiducial transmission spectrum of V1298 Tau c (black points) compared to the median retrieved models with (blue line) and without (orange line) enforcing informed stellar heterogeneity priors, each binned down to R = 100. The 1σ, 2σ, and 3σ model uncertainties are illustrated by the colored shaded regions. We achieve excellent fits to the observed spectrum, which are largely insensitive to the exact stellar heterogeneity parameters. ✎
