Top Left: Radial profile of Capotauro re-centered to its brightest pixel (black line) compared to the median profile of 89 empirical PSF sources injected in the F444W image and flux-matched to Capotauro (in blue; the shaded area represents the 25–75 percentile range of the 89 profiles). An empirical CEERS F444W PSF profile (red line) is also displayed, as well as a spectroscopically confirmed F444W-detected BD in CEERS (green dashed line; JWST/NIRSpec MSA ID 1558; Holwerda et al. 2024). Uncertainties are calculated as the standard error on the mean flux within concentric 1 px annuli. Top Right: Lower limit on Capotauro’s break strength (dashed orange line) compared to that of the Sonora Cholla cloudless BD atmosphere models (circles) for different effective temperatures, color-coded by their surface gravity value (i.e., log g). Bottom: Rescaled F356W fluxes of the 41 χ_red² < 2 Sonora Cholla BD templates versus their effective temperature, color-coded by surface gravitational acceleration. These templates are compared to Capotauro’s 1σ upper limit (orange dashed line). For reference, we provide Capotauro’s ATMO BD template best-fit temperature (T = 300 K), represented as a black dotted line.
