Observed NIRSpec prism spectrum of J0647_1045. Top: 2D spectrum showing the bright Hα, Hβ, and [O III] emission. Bottom: 1D spectrum (corrected for Galactic extinction) with several identified lines labelled. The observed wavelengths are shown in μm on the top axis, while the rest-frame wavelengths are plotted in Å on the bottom axis. The NIRCam photometric fluxes in a 0.5 arcsec diameter aperture in the UV filters F115W, F150W, and F200W are shown as blue stars with the NIRCam bands shown as error bars. Optical/NIR filters F277W, F356W, and F444W are similarly shown as pink stars with error bars.
