(a) Photometric redshift likelihood distribution, P(z), for the central core (0.16″ radius aperture) derived with Bagpipes. This P(z) is consistent with that shown in Fig. 1. (b) P(z) derived with Bagpipes using a 0.7″ radius aperture, showing a second redshift solution at z ∼ 1.6. (c) EAZY SED fitting results for the central core (0.16″ radius) with the redshift fixed at z = 1.6, indicating a poor fit with χ² = 46. (d) Bright clump (clump 2, marked with a black circle) detected at 5.5σ and 7.5σ in the F606W and F814W bands, respectively. The EAZY fit for clump 2 shows a broad redshift distribution with $z_{\mathrm{phot}}=1.{65}_{-0.02}^{+2.11}$, which suggests it may be a foreground object.
