Best-fit EAZYPY photometric redshifts for the Cosmic Gems Arc using the photometry measured in both elliptical Kron apertures and isophotal source segments. The top plots show results using the non-PSF-matched photometry, while the bottom plots are for the PSF-matched photometry. The measured fluxes are shown as blue data points or triangle upper limits. Nondetections are plotted as upper limits at the 2σ level. The best-fit EAZYPY SED model is shown in orange, with squares indicating the expected photometry in a given band. The best-fit EAZYPY SED for the low-redshift (z < 7) solution is shown in green. To the right of each SED, we also plot the P(z) posterior redshift probability distributions. The Cosmic Gems Arc has a best-fit photometric redshift of z_phot = 10.2, with low-redshift solutions ruled out at high significance.
