A benchmark Sonora Diamondback fit to β Pic b. The fit combines the GPI Y/J/H spectroscopy, GRAVITY K-band spectroscopy, broadband literature photometry, and synthetic CPI-C VIS4+NIR4 photometry. The blue curve is evaluated at the marginal posterior medians, and the gray curves show posterior draws. The yellow and red points mark the synthetic CPI-C VIS4 and NIR4 measurements.
