Photometric redshift estimation for the CI using EAZY and BAGPIPES. Black circles denote the observed photometry. The best-fit models (spectra and photometry) from EAZY and BAGPIPES are shown in green and blue, respectively. The derived photometric redshifts are 6.12 ± 0.17 (EAZY) and ﹩{6.28}_{-0.13}^{+0.14}﹩ (BAGPIPES). The inset panel shows the redshift posterior probability distributions. The vertical dashed red line indicates the spectroscopic redshift of the Cosmic Spear.
