The available photometric and spectroscopic dataset of LAE-11. (upper) A composite image of LAE-11 consisting of the NB926, F125W and F356W photometry, the 2D and 1D NIRSpec/PRISM spectrum of LAE-11 located at z = 6.6405 ± 0.0005. The uncertainty on each pixel of the 1D spectrum is represented with a red line. The vertical dotted lines represent detected emission lines. From left to right: Lyα, Hβ, [OIII] doublet, and Hα. The spectral energy distribution of LAE-11, encompassing photometric data from Subaru/HSC (blue squares), HST/WFC3 (purple circles), and JWST/NIRCam (pink triangles) is shown on top of the 1D NIRSpec spectrum. (lower)NB926 image, 2D and 1D Keck/DEIMOS spectrum of LAE-11 on the left with F356W image, 2D and 1D JWST/NIRCam WFSS spectrum of LAE-11 on the right. The uncertainty on each pixel in both spectra are represented with a red line. The vertical dashed lines mark the position of the Lyα in the DEIMOS spectrum, Hβ and [OIII] doublet emission lines in the NIRCam spectrum. The vertical shaded regions in the DEIMOS spectrum represent the skyline regions.
