The combination of JWST NIRCam photometry, HST photometry, JWST NIRSpec G395M spectrum, JWST MIRI-LRS spectrum, and MIRI photometry covers 91% of the bolometric luminosity of WD 0806 b. We also include the transmission curve of the broadband filters that share the same colors with the photometric points. The plotted photometric points from short to long wavelengths are HST/WFC3 F110W, NIRCam F150W2, NIRCam F200W, NIRCam F356W, NIRCam F444W, MIRI F1200W, MIRI F1500W, MIRI F1800W, and MIRI F2100W, respectively. The MIRI photometric points are adopted from M. Voyer et al. (2025), and the HST F110W are adopted from K. L. Luhman et al. (2014).
