Results of the forward modeling of β Pic b using the most recent spectro/photometric observations of the planet (including CRIRES₊) using BT-Settl. Top panel: spectra (points) and photometry (squares) of β Pic b alongside a R_λ ∼4000 spectrum extracted using the best fit parameters for the inversion. Observations have been re-normalized using the analytic scaling factors computed during the inversion. Associated residuals are shown below. Dotted lines represents the ±σ (68%) confidence interval. Bottom sub-panels: xoom versions of the top panel on GRAVITY (upper left), SINFONI (upper right), CRIRES₊-K (lower left) and CRIRES₊-M (lower right). Similar to Landman et al. (2024), each CRIRES₊ spectra are shown smoothed by their retrieved broadening to show the planet features more clearly.
